What is the clearence difference between a d44 and a 10b? What is the difference between a d60 and a 10b? I think i might have a d60 up front... since it only had 10 bolts i figured it was a 10b but it has 1 inch less clearence then my rear 10b and looks a hell of a lot different. Is there such thing as a 6 lug d60? thanks.
