If you've got an AOD, you need a 164 tooth. Only the C-4's used 157's and then only the ones with the correct 157 tooth bell. Some C-4's also used 164's and the Stang II unit used a 147 tooth.

Like I said before, a C-4 can use either, depends on what bellhousing it's got.

well i dont have the C4 yet and i plan on getting one from TCI. so with that said are you saying i can use either bellhousing with a TCI tranny? and does a bigger bellhousing mean tighter fit under my car? what are most of you guys running the large or small?
