All Inclusive list of Bolt sizes on CJs

Alright, Ive had this idea for a while and I think it would be EXTREMELY helpful to all for that quick reference. I would like to document EVERY bolt size and type (grade 8, 5, stainless, etc) that could/should be used.

I would be more than happy to keep track of the list and update it and catagorize it. Im thinking split it into two main catagories, Body and Frame and Drivetrain. With subcatagories for engines, trannys, and axles. Of course it will be specific to CJ5, 6, 7 and 8. Im going to try and keep it as organized as possible.

I know it sounds like a large undertaking but I think if we all contribute it wont be to bad and more than worth it!!

cheers!

Ben

Im glad someones thinking along these lines. Seems like we need a nice spreadsheet per year for each. Im going to start with the bolts I am working with now on the front end and start keeping tract. As im putting things back together I wish I would have done this as I was taking it apart! D'oh!

So how about the years prior to AMC since you've listed CJ6 and CJ5.

There were more engines than just the 258 and 304.

Good luck with this!

CJ8 never had a 304 from the factory. Some have been swapped in, but it wasn't a factory option. CJ5 and CJ6 also had F134, 225 V6 and AMC 232 engine options. CJ7 also had AMC 232 engine option.

But why stop with CJ5? Why not CJ3B, CJ3A and CJ2A?

I thought that they all had 258s but that the 81s had narrow trac axles. Is this incorrect? I would love to find a cj8 with an original v8, that would be awesome!

Saw the edit. Oh well. A v8 cj8 would be cool.

4cyl or 258 only, no 304 was ever offered in a CJ8. Yes, 1981 was narrow track.

CJ-8

Introduced in 1981 and produced through 1986, the CJ-8 Scrambler was a pickup truck version of the CJ-7 and held many of the characteristics of the CJ-5 and CJ-7 of that era. It featured a 103 in wheelbase and a pickup bed. Only 27,792 were built in the 6 years of production.
Drive Train

Engine

In 1981, the CJ-8 was offered stock with the GM 151 I4 engine and the 258 I6 and 304 V8 were optional. The last year for the 304 was 1981. The GM 151 was replaced with AMC 150 I4 in 1984 through 1986.

Transmission

The SR-4 and T-176 were used with the I4 and I6. The T-176 was used with the 304. After 1981, the T-4, T-176, and T-5 5 speed were used. The TF999 was used with the I6 and V8 and the TF904 was used with the I4.

Transfer Case

The Dana 300 was the transfer case used in the CJ-8.

Front Axle

The Dana 30 was always used in the CJ-8.

Rear Axle

The CJ-8 used the AMC 20 rear axle.

The standard engine was the Pontiac-built 82 horsepower 4 cylinder 151 cubic inch engine, optional engine was the 110 horsepower in-line 6 cylinder 258 engine. The AMC 304 and 360 were not given as a factory option. http://scott_cj8.tripod.com/scrmbpg.html


If you find a factory 82 CJ8 with an original 304, be sure and register it at the Scrambler registry. There are over 8,000 1981 Scramblers registered there and none list a 304 as a factory equipped Jeep. There are plenty that have 304 swaps. I'm not saying definitively that one doesn't exist, but it's never been documented to my knowledge. http://www.jeephead.com/1981_cj8s.htm
