60's cad ford 9" rear end w/discs question

ive seen some profiles with mention to you on ford 9's in early cads.What vehicle are you pulling these from with discs brakes that fit the width of the vehicle?or are you getting blank 9's with an aftermarket disc brake setup.thanks much

They are custom built units from Currie Ent with Wilwood brakes. They are not that easy to do nicely either. The factory style brackets are tough to mimic.
