Depends on year and trans, there are some differences, some are 10 1/2 clutches, some are 11, some are 1 1/8 thickness, some are 1 1/16 thcikness. There is quite a lot of back and forth interchangability in there, some will, some won't. This probably sounds as confusing as it can be. At least they are all 10 spline!
