The bellhousing from a 2.8 to a SB are way different. The 2 bolts on either side of the housing go up at an angle inward on one, and are directly over top on the others, and the upper 2 bolts are farther apart from one, than the other. I'm not 100% sure right now as i'm tired as hell from the christmas day past. lol.

Edit: also if IIRC the SB trans bell comes to somewhat of a point that the top where as the 2.8 trans will be a straight line from bolt to bolt on the upper 2 bolts.
the trans part i got a tranny its a th350 the 2.8 wont work cause it is a 60 degrees v6 4.3 is a 90 degrees along as the SBC motors. what im saying i though you still need swap mounts. cause the motor mounts have to forwar alittle. im pretty knowledgeable on my swap, i know all about the trannys
