Frame/Body question from a newb

I need advice- Thanks in advance

I bought an ’86 CJ7 a couple weeks ago, and then a neighbor GAVE me a ’79 CJ(not sure if it is a 5 or a 7). Anyway- I am trying to figure out how much of the two are interchangeable? All Google searches just turn up forum discussions, no solid charts or lists of what is/is not interchangeable. I am really hoping the two bodies and frames are interchangeable.

Please advise.

First thing, if the 79 is a cj5 it will be around 10 inches shorter, and the door will have a hump, not the U shape of a cj7.

The 7 guys will have to help me out with this, the only major difference I know of is the frame change in the early 80's. They should be interchangeable but probably not without modification.

If the door openings look the same, you can swap both the tub and frame between them.

The axles changed in 82 on both so the front shock mount will be different. But a 5 and a 7 are two different bodies and two different frames, as was said.

Thanks everyone. I work in Maryland and the Jeep is in Delaware. I will check it out tonight when I go to Delaware and see if the doors are the same.

Here are the two jeeps. If I had to make a guess I would say the 79 (one with hard top) is CJ5... Any other opinions out there?

Both Jeeps are CJ7s. The axles are not interchangeable. The '79 has a narrower wheel stance. If they are both 258CID inline sixes, many but not all parts are interchangeable.

The '86 is a 258 inline, w/ manual tranny, the '79 has a 304 V8 automatic tranny. Ideally I would like to keep the 304 V8 in the '79 and add the manual tranny into the '79- is this possible?

It's possible, but depending on which model of manual trans the '86 has it may be a step backwards. The only manual trans offered in the last years of production with any kind of durability was the T176. The rest are classified as light duty transmissions and aren't worth the hassle of swapping, especially if you plan on running larger than stock tires with the stock geared differentials.
