1974 Dodge Dart Magnum Swap

Yeah I'm using all the old pulleys off my 318 so that might be the problem. The bracket I'm suggesting is just a reproduction of a stock piece. You might want to find a 70's small block to rob all the pulleys and brackets off of. Best no a/c to avoid the same problem. Your fabbed alt. bracket looks like 1/2 of my old bracket flipped upside down. It also may be you might have the wrong bracket for the PS pump you have. Federal/Saginaw and that may be why the holes are not lining up cause a small block Mopar should work with another SB Mopar.
