iv called around and iv been told that i may need a "hub" to mate the steering pump up to the vacume pump, and mybe a gasket of some sort. anyone know what this is all about. noone that i had talked to could give me a straight answer and my local dodge dealer wont tell me anything about it unless i buy a powersteering pump from them. i have a steeting pump from PSC, but nothing else, not even direction. help
