GLWS. Looks nice. Question on these bellhousings. Were there some 621 bellhousings made for trucks with a larger center sections, or were they different casting numbers?

Thanks. I’m pretty sure the truck applications had a different casting number and were made to accept a 12” clutch, so it’s physically different in appearance aside from the larger center hole.
