the 5 bolt J30 diffs are older anyway and will have more miles on it.
6 bolt are bolt on but like 240brisx said you'll need to swap the cover.
but this guy is looking for a welded diff. so back on thread topic. TTT Good luck with the search..
Blake - That diff you claim to have wouldnt be the diff w/o the shafts that I gave golfie that you promised to have welded for him would it?
