Rear seats for a CJ will fit. locking front hubs from the flatty‘s work (warn 29062 10 spline). yj/tj door hinges work with a little bit of wallowing one bolt hole about 1/4”, then cut your own door and use the hinges to have an easily removable door. CJ rims bolt right on, need 5x5.5 bolt pattern and that large hub hole. CJ fender flares bolt right on although the fronts on the fender curve aren’t an exact fit. Flare protrudes out a little. Jeep Dana 44 (CJ thru TJ) internals will swap for the Roxors. Have to swap everything. Can’t use a Roxor ring and pinion on a standard 44 carrier. But a standard 44 carrier and ring and pinion will go right in the Roxor diffs. Be sure not to get a JK 44, those are a larger ring and pinion and won’t fit. CJ/YJ windshields can be made to fit but the roll bar will need to be reworked and the seats will likely be too tall as the windshield will be lower in total height. All of this info is detailed elsewhere in this forum. Search for the specific threads and you’ll find more detailed info.
