1977 CJ5 vs. 1975 CJ5

Looking at a donor CJ for my '77.

Is there any difference between the body of a '75 and '77?
I know the frames are different, boxed in and not boxed in.

Any help would be great.

There's a lot more differences in the frames other than boxed vs. non-boxed. The '75 rails are the same distance apart from front to rear for starters.

The tubs are different. The floor, firewall, and body mounts are quite different.

You will find a lot more aftermarket support for the 76 and newer CJs than the older ones. That was at least my experience when trying to decide between a 75 and 76 when I started looking at parts.

i think the 75 is 3 inches shorter than the 77 would be. if you are concerned with after market support, cj5s dont have much no matter which way you go. cj 7's have way more support as far as bolt on parts.

The 75 will have a 30 spline flanged D 44 rear..........possibly the t-15 or t-18 4:1 trans...........if it's just for parts this could help diversify what you already have in the 77.............like others posted bodies are not that close at all.

No it isn't. The wheelbase change occurred in 1972.

Like what? Anything for a CJ7 suspension, engine, tranny, axles, etc are all compatible. The only things that aren't the same are the tub, rollbar and rear driveshaft. 76+ CJ5's have just as much aftermarket as their CJ7 counterparts. Furthermore, that wasn't the question asked by the OP.
