Bellhousing

Yes call Brewers they will give you the details for what works, ie bell, fork bracket (pivot) , fork, Z bar. They have the knowledge and all big and small parts needed.
If not mistaken the LA engine SB bell will bolt right to the poly. I also plan to use a 10/1/2 fly. I will do that in a 62 Dart (B body) if I ever get to La. for the trade for the engine.
It fits with about 2” on each side,I’m fabricating fenderwell headers so that won’t be an issue manual brakes no problem there.
