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?
