I have a quick question, what bolt pattern does my car, which came frome the factory with fornt disks, have? 4.5"? And is that is the same front to back right? Because I'm reading all these posts about bolt circles and they say that A-bodies had small bolt patterns. The reason I'm asking is that I'll soon be swaping in a b-body 8 3/4 and I'm wondering if my front and back will have 2 diffrent bolt patterns then. The way i got it and the way it sits there is an adapter on the rear to get the rims to bolt up, well either that or it's a funky looking spacer. Thanks, I feel like and idot asking this qestion, i'm sooo confused.
