Hey guys, I'm cooking up an evil plan to put discs on the back of a nine inch I have just because I have to modify the **** outta stock backing plates to make drums work, and discs look better, but anyway, here's he question. Does Any one Know the distance between the caliper mounting pad and axle flange on a thirdgen?

 

the folks in the brake board probably have more of a chance answering this one.
