The typical pick-up truck (1/2 ton, 3/4 ton) with a 4sp behind a typical SBC/BBC have a larger bearing retainer opening (5") compared to the cars (4 5/8").
http://www.5speedtransmissions.com/GmTruckBellhousingInfo.pdf shows more detail, including pics. These bell housings can be used, but will require a special made adapter ring to accommodate the larger opening which in turns requires machining to your bearing retainer to "lock" the adapter ring in place. Beyond that, I'm pretty sure the truck bells are suitable for use in our cars. Hope that helps a bit.
