10 1/2" Clutch Upgrade

I think the 482 bellhousing is what I used in my 64. It has the small hole in it so your trans has to have a small input bearing retainer, about 4.3" in diameter. If you have a larger retainer you either have to swap to a smaller one (I think this can be done depending on the trans.) or machine the hole in the bellhousing to fit the larger retainer.
