Question:

i see that your kits for the final drive gear set is for the manual only. my question is why is that is there a difference in the diff housing for the gear set because if thats the case i can get my self a manual trans diff and build that, but if it has something to do with shift points on the trans then ya i can get a retune. - KEVIN

Answer:

Hey Kevin, it's just because the AT cars had a slightly different differential. You can swap a MT diff into an AT subframe though.
