On March 1, 2018 I bought a 1984 Jeep CJ-7. Here is my build thread.

Updated Apr 18, 2018. Here is the jeep as it sits now…
Why a CJ-7?
Since selling my 1990 Jeep YJ back in 2008, I have been waiting to get another old Jeep.
While newer Jeeps are safer, more comfortable, and reliable, they also lack the personality of an old Jeep. Since this CJ-7 is not my daily commuter car (I work from home), I had the liberty to get something less practical.
I read this once regarding old Jeeps:
“I don’t own a Jeep to be practical — driving almost any other vehicle makes you realize just how impractical Jeeps are. But on a sunny day with the wind in my hair, there isn’t any vehicle that can put a bigger smile on my face and I’m like a kid again thinking of excuses just to drive somewhere. Sometimes I pause in the garage just to look at it.”
My budget for the Jeep was enough that I could have found something fully, frame-off restored and built up. But instead I opted to get something that was roughly half my budget: something in excellent mechanical condition but that didn’t yet have all the upgrades I wanted and that still needed a little bit of wrenching. This way, I could spend the remainder of my budget on doing the exact upgrades and mods that I wanted, in order to not only enjoy the process of doing the work myself but also to end up with a Jeep that had the exact mods I wanted.
When looking for the CJ, I wanted something in orange, red, or green that came with a hard top and matching steel doors.
I set up an IFTTT recipe to monitor Craigslist and let me know of any new listing related to “CJ” within about a 600 mile radius of Kansas City. On Feb 27th I found the Jeep I wanted. It was located in Wichita.
After texting with the owner we landed on a pretty great price, and I drove down there on Thursday March 1 with my dad to pick it up.
At the time I bought it, it had these mods / upgrades:
- Rebuilt AMC 360 V8 with mild Cam
- Holley Performer intake
- HEI Distributor
- Hedman headers and dual Flowmaster exhaust
- 650 Holley double pumper carb
- New Master Cylinder
- BDS 2.5” Suspension lift
- Chevy 904 (or possibly A999) automatic transmission (a.k.a. TorqueFlite) with gear ratios of 2.74, 1.54, and 1.00 (or possibly of 2.45, 1.54, and 1.00 if it’s the A999).
- B&M ratchet-style Megashifter
- Tabor 9K winch
- Steering box brace
- Smittybilt front and rear tube bumpers
- Rhinolined tub
- Restored dash with radio slot delete
- 32×11.50×15 BFG Mud Terrains on butt-ugly 6-spoke hot rod wheels
The CJ also has:
- Wide Track AMC 20 rear axle with 2.73 open gears (i.e. Code D)
- Dana 30 front axle
- Dana 300 twin stick transfer case
(My dad and I, picking up the CJ-7 in Wichita on March 1, 2018)
When we got to Wichita, we found out that the CJ-7 gets a whopping 6 MPG. There was no way we were going to drive it back to Kansas City. And my dad’s Lexus didn’t have a tow hitch hookup so we couldn’t get a trailer either.
I found a place that transports cars between Wichita and Kansas City and they do routs every day. We were able to drop the Jeep off with them that night and by the next morning it was delivered to a lot that was only 5 miles from my house. Cost for transport was just $175, though I paid $200 because I only had cash in $100 bills after buying the Jeep, and so I tipped the guy $25 for allowing us to get onto the transport at the last minute.
The next morning, the Jeep had been transported to Kansas City and was parked in my front driveway…
Build Wishlist / To-Do List
Currently, the additional mods and work that I want to work on include:
- Smittybilt Rock Sliders (done)
- 33×12.50 BFT All Terrain TK02 tires (done)
- 15×8 Pro Comp chrome wheels (done)
- Chrome front grill (done)
- Grant steering wheel (done)
- Tachometer (done)
- Replace the transmission shifter (the B&M ratchet shifter is not functioning properly)
- New axle gears (from 2.73 to either 3:73 or 4:10 and a locker in the rear)
- Variable Ratio Steering Box (because highway speeds)
- YJ Family Roll Bar Upgrade (because kids)
- Add all the rubbers and weather strips to the full steel doors (done)
Gas tank upgrade to a 21 gallon (because 6mpg!)After getting a new carb and tuneup, the Jeep now gets 10+ MPG. Yay!

Took the Jeep to Stomper’s Off Road shop. A place that specializes only in Jeeps. When parking it, was the only jeep older than a few years. There were a whole bunch of black Rubicons in the parking lot, and one orange CJ…
After a 3-hour inspection at Stomper’s, this is the list of work needs to be done to the Jeep:
- Front drive shaft bent (u joints bad as well)
- Rear pinion seal leaking
- Transmission leaking from electrical plug
- Front passenger U joints failing
- Small amount of water in oil breather
- Missing and loose valve cover bolts
- Plugs and wires need replaced
- Electric fuel pump possible small leak
- Doors very loose and latch and door surrounds
- Carb and Timing need tuned due to elevation change
- Shift linkage not set correctly needs addressed
- Small antifreeze leak from petcock area
- Oil Pan bolts loose… not to torque
- Transfer case leak
All in all, it’s in very good shape. Many of the leaks are normal and small.
The work I’ll have Stomper do is:
- Full tune up (plugs, wires, cap, timing, carb)
- Front drive shaft and U joints
- Front Passager U Joints
- New Fuel Pump
- Checking and tightening all the bolts on the oil pan, valve covers, and around the engine.

Today the Smittybilt rock sliders were delivered, along with a new breather for the intake and a clean (and bigger) air filter for the carb.
I started work on installing the sliders, but, alas, they didn’t come with any mounting hardware so I drove to Lowe’s to pick up some bolts.
Side note: I thought the Jeep had been frame-off restored. But after trying to remove the body mount bolts on the driver’s and passengers side, it’s clear that they’ve never been touched before. There was a ton of rust on the bolts. And the passenger-side, center body mount is stripped out — the top nut is spinning, so I’ll have to drill an access point so I can hold the nut while loosening the bolt.
(About to mount the passenger-side rock slider.)
The driver’s side was much simpler. I was able to loosen the front two bolts. The third one (closest to the rear tire) is not even there. Then I was able to lift the body up using my hydraulic lift and a 2×4, put the rock slider in place above the center bushing, and then lower the body back down and put the two bolts back on.
Here is the driver-side rock slider in place but the side body mounts are not yet drilled in.
With the exhaust pipes right under the doors like that, these rock sliders won’t really do much more than look cool and serve as a step to get into the Jeep.
New Carb Filter and Oil Breather
Wednesday, March 7, 2017
Replaced the 10″ carb filter along wit with a new, matte black cap. Also replaced the oil breather, as the old was was fully saturated and blowing oil onto the underside of the hood.
Finished the Rock Sliders
Sunday, March 11, 2017
Using a Dremel, my dad I were able cut out a small section of the body just under the passenger seat in order to access the top of the center body mount bolt. From there we were able to get the top bolt nut to hold in place in order to loosen the bolt and finally install the passenger side rock slider.
New Shift Knobs for the Dana 300 Twin Stick
Monday, March 12, 2017
Picked up these billet aluminum shift knobs for the Dana 300 so myself or anyone else who is driving, will know how to control the transfer case.
Also got the door rubbers installed. (This is the best upgrade so far! Haha.) The doors no longer rattle like crazy and the Jeep is a bit more temperature controlled (as much as a CJ-7 can be that is).

Ordered custom license plates that say “BLANC”. My grandpa had these same custom plates on his old trucks in Colorado. Continuing the tradition here in Missouri…
Mar 15, 2018
The Jeep has spent the better part of the past two weeks in 3 different shops getting a tuneup (plugs, wires, carb tune), new front drive shaft, new front break lines, having the tranny inspected, replacing the carb, and more.

Tires and Wheels
March 21, 2018
Had 4 Wheel Parts put on these 33×12.50×15 BFG All Terrain TKO2s with Pro-Comp wheels. 👌
Chrome Front Grill Overlay
March 22, 2018
The chrome grill overlay was a tossup. I love the look with and without it. But I decided to with it as it matches with the polished wheels and I think it gives the whole jeep a bit more of a clean and classic look. I’m not trying to build a mean rock crawler or mud queen.
Here’s a few photos of the Jeep with the headlight and parking light housings removed out and the winch wiring pulled out, me grinding a tab off the chrome overlay, and then the front end once all finished:
While this should have been one of the most simple updates of all, it still took a few hours and required the use of a grinder. You can see the Instagram slideshow here.
New Front Brake Lines, Intake Gasket, Fuel Filter, Wiring, and Carb
Mar 28, 2018
A few days ago I took the Jeep in for the state safety inspection and a few things failed…
Most notably was a cracked break line at the front passenger side. Yikes! Also a failing fuel pump, a few leaking coolant lines, and a leaking intake gasket. It was a no brainer to replace the intake gasket before any of that coolant began finding its way inside the engine. (That was the deal breaker for my old YJ.)
And, while they had the intake removed, they found some it turns out that 2 of the vacuum hoses on the Holley carb were completely plugged, and one of the floater gaskets had fallen down inside the barrel. Bad news. It as a tossup between rebuilding the carb and just replacing it altogether — I opted for the latter.
The carb tuning that I paid for two weeks ago turned out to be a complete waste of money. Oh well, that’s how it goes with a Jeep.
Attempted Installation of a New Shifter
Mar 29, 2018
Today the new Lokar shifter arrived. And it’s awesome. Except for one thing…
I took it over to my mechanic so we could get rid of the horrific B&M Ratchet shifter and replace it with this new one. Alas, it’s completely the wrong size.
I had ordered a 16-inch double bend shift lever, but there was no good place to install it in the Jeep. So I’m returning it and have ordered a 10-inch single bend lever instead.
Shifter Finally Installed, Etc.
Apr 16, 2018
After 3 weeks at the shop, the new shifter is finally installed! It turned out to be a simple, $5 part on the transmission itself. The TF904 has two types of lever attachments: one for use with a column shifter (“3 on the Tree”) and one for use with a floor shifter.
The Jeep must have originally had a column shifter and the previous owner left the wrong lever when converting to a floor shifter. And that’s why things were messed up. But now the new Lokar shifter is installed and works great.
Also, the engine temp sensor is working.
And… with the new carb in place the Jeep is getting around 15 MPG!
New Headlights and Parking Lights
Apr 16, 2018
Today I installed new headlights and parking lights. The parking light assemblies were the original ones — they were rusting out and the plastic covers were all fogged. The new ones were simple to put in, are much brighter and clearer.
The headlights were also the stock originals. And driving at night it was like having two small little flashlights pointed toward the road. They barely illuminated anything.
I replaced the headlights with an all-new assembly. I put in Hella e code headlights along with higher wattage halogen bulbs. The bulbs connection required a ceramic adapter because the lights can get hot.
The difference is, no pun intended, like night and day. The new housings and bulbs give a full spread of light on the road. Much safer.
New Tailgate Cable
Apr 17, 2018
I replaced the tailgate cables. The left one was missing, and, oddly, CJ-7 tailgate cables are too long. Which means that when the tailgate is open it hangs down at an angle. So odd.
I found some 16-inch cables for a Ford Ranger and they worked perfectly.
As of April 18, 2018… here’s what’s on the docket…
Next week, the Jeep will be getting new rear end. And by that I mean new, one-piece axles, re-gearing the differentials, and a locker. When rebuilt, the AMC 20 Wide Track is arguably as strong as a Dana 44. So long as I’m re-gearing it, I might as well rebuild the rest of it too… (haha. That’s what they all say, right?)
I was originally wanting to get an ARB locker in the rear, but it costs nearly as much as everything else combined. So I’m going with an Auburn Pro limited slip instead.
As for the gear ratio, believe it or not, I’m still undecided.
The current diff gear ratio is 2.73 and the stock tires were 235/75/15 (or 29 inches tall)
With new tire size of 33, the “back to stock” diff gear ratio should be 3.10:1 (because new tire height divided by old tire height multiplied by gear ratio equals ideal new diff gear ratio). So:
33/29 * 2.73 = 3.10:1
Then you bump it up to the nearest common ratio — in this case, 3.54:1 — and that is the best starting point for new gear ratios in my Jeep. But… since it rarely sees highway, it would be advantageous to get the lowest gears possible without completely sacrificing it’s daily drivability.
Thus I want to re-gear the diffs to at least 3.73 if not 4.10.
Now that the Jeep is back with the new shifter, carb, and working tachometer I’ve been able to confirm that the gears are, in fact, 2.73. I should be okay going with the 4.10:1 ratio, but it will mean my top highway speed will be 65 and I won’t have much passing power. But, the Jeep is not really a highway car, so I think I’d rather have more low-end power than top speed. And, if I ever end up replacing the transmission one day I won’t have to re-gear the differentials.
Also on the to-do list: install a 1-inch body lift; build a hard-top hoist and holder in the garage; look for a YJ-style family roll cage; put in a variable ratio steering box; install a center bench seat; and probably a few other things.
I update this page about once a week. You can follow me on Instagram for more photos and stories about the CJ-7.
