As far as I'm aware, there are only 2 sizes of front retainers. The 'car' retainer is smaller, and more popular. It is also the same size as the retainers used on the old SM318 3-speeds, in cars or pickups.

jimfulco Some vehicles require a different bellhousing from others due to clutch linkage placement, etc. If you're using the 11" clutch, you'll have to use the larger 168-tooth (14" diameter) flywheel, and that wheel won't fit into some of the smaller bellhousings that were designed for the 153-tooth (12-3/4" diameter) wheels. For example, first-gen Camaros used the small bellhousing with casting number that ends in -403, or the large housing with a number that ends in -621. The 11" clutch won't fit with the -403.

poncho62 Big Block and Small block bellhousings are the same pattern. The flywheels will also interchange.

Bellhousing for 402 bb

I am changing a 70 402 bb to a 4 sp. the flywheel is or will be 11". Will this take any GM bellhousing for that year or is there a certain bellhousing I should be looking for. Also the same for the flywheel.
