Ok, just get a measument of the outside diameter on the big side, where its bolted to the trans. Should be 5.125", If so the bellhousing part number is 3743859. If you look on Brewers Performance website you will see all the diferent bellhousings, this is the one for an A body with 10 1/2" clutch. You will be running a 10 1/2" clutch with a smallblock.
