I've tried searching with questionable results. I'm trying to figure out if my 86' 305 will have a one or two peice rear main seal. Thanx in advance.

It depends if it is the earlier in the year if it has a one piece, or that is what I was told by the motor replacement co. I'm using. They said that the one piece came out later in the year and that some of the earlier 86's were still using the two piece. I know that does not help you alot.
