yj body on a TJ frame
Not that hard. Several have done it and it came out great. The back four mounts line up. The front mounts will need to be moved about 3 CM. The gas tank works if you use flex hoses. You might have to trim the inner front fenders a bit to clear. I have a TJ frame in my back yard that I am in the process of doing this swap. I have done a lot of measuring and I think this will be an easy swap. There is a Lincoln here on a F250 frame and that was not that hard. Anything can be done it just depends on how bad you want it.
