I picked up a 9" yesterday, and actually I have 2 questions, what should the width be from inside the brake plates and the pinion is a bit off center. Will that make much difference? Will I be going through U-Joints? It came out of a 1975 F-100. It also has 3:25 gears. Could I get into the 13's high 12's with these gears and the motor I have in my sig? Thanks.
