Typically large bolt pattern axles move the flange out 3/16 to 1/4" because they have thicker flanges than small bolt pattern axle flanges.

I'm not intimately familiar with Dr Diff rear rotors, but are they thicker where they mount to the axle than the drums you took off that 8 3/4 ?

If so, how much? If so, they makes you rear a little wider too.



Just did a rough measurement with the rearend in the car using a tape measure. Rotor face to Rotor face is ~59". So if a stock A-body rear is 57 1/8" drum-to-drum than I added an extra 15/16" on each side? ~24 mm? Does that sound right?



Check with Dr Diff who you bought the axles and brake kit from.

Is the center section out of the rear? If not you have to bend the tape measure around and give you a bad measurement. Better to take a long straight edge against the end of the axle with the rotor clamped on. Then extend the straight edge to the floor. Mark floor. Then do some on other side. Then measure between marks on floor.

Your rear end has 43" between leaf spring hole centers correct? Not 44"?
