And I need to know what parts I need to do this swap from an A4. I'm doing this swap with my father in law and he is an experienced mechanic. I am a mechanical novice and have little experience wiring. I guess I just need a list of what I need from the donor car that isn't on my A4 car. I know I'll want the rear end gear but what about less obvious things like the drives haft and crossmember. Master cylinder? Exhaust? I've seen people modding the wiring harness but would it be easier to pull the harness from the donor car and swap it also? Sorry I have so many questions. I found tons of threads for swapping this into other cars and older for bodies but I haven't had much luck finding many swapping 98-02s. Maybe I'm looking in the wrong places but anyway I appreciate it.
