pulley problems
Im putting vintage air on my 71 sb.It already has power steering.The pump has the cast iron pulley on it.I have a 2 groove crank pulley.I put the add on pulley on it to make 3 grooves just like the factory.Now the the pump pulley needs to come fwd a 1/2 inch to line up with the add on pulley.I cant shim the pump enough to line up with out the bolt hitting the alt belt the rides just in front of it.Is there another pump pulley the factory put on for this reason.I seen a stamped pulley and a cast iron pulley on them.
