Does a my engine that is a 472 have the two piece rear main seal? Been trying to look it up and I am having a hard time finding a solid answer. Need to know before I start buying parts and wrenching at it. If its a two piece I will be doing it at home, if it is a single piece or the rope seal I will have to take it to my father in-laws garage.
