yup the front arch on the 2wds is definitely higher than the front of an ifs 4x4 rig
i was actually looking into the 4x2 to 4x4 conversion awhile ago when i first got my 4x2....
i have a frame from a 4x2 1985 for sale, it was involved in a rollover and the body mounts did shift a little bit probably due to my bodylift, but it doesn't look to be bent much if at all
