Hey does anyone know who can install some 3.73 gears in my 1994 stang located in Arizona????????? I heard of AMP but I have seen alot of negative reviews on them so I;m kind of concerned about that. Also has anyone done this job themselves, if so how bad was it compared to a H/C/I and tranny swap(All of which I have done by myself). Also would it be easier to just find a whole rear end with the 3.73's already in it. Thanks everyone
