Converter cover
Thanks for the info! The difference in the covers is the cutout section that meets the engine. You can make the sbc version work, but you do have to do some grinding. I have done this in the past, just trying to find a correct one. There were different part #'s for the cast aluminum version that were specific to sbc or bbc. Mid 70's to 1984 were a part#14038651 sbc only, 81-90 (K & V series) was a part#14024996 BBC only, and starting in 1985 and going through 1990 there were a couple of different sbc #'s 15522023 & 15522125. There are casting #'s on them that sometimes match or a lot of times I can cross the casting #'s over. I am a parts manager for a GM dealer so sometimes I get caught up in the #'s deal! There may also be other versions of them out there, but these are the ones I am most familiar with! Thanks again for everybody's input!
