i was wondering if the rotors from the 97 pontiac fit in the square port m90??
or if any of these gm cars can be use on the m90 on the oval port?? or both?? any one thanks in advance
Any GM M90 rotors should swap .... but you have to move a locating dowel or some such thing. Do a search, it has been discussed here. A search for "GTP rotor pack" or something like that should work fine.
