I run a factory Ford 9" out of a Lincoln Versaille, a small car on the Granada/ Monarch platform, which is literally a "bolt in" for the Mopar A bodies. The pinion is offset, the spring pad centers are about 1/2" (?) wider than Mopar, and the axle is a little wider. I made up for it with wheel offset. I've forgotten how wide, I'll try 'n find out.
I would NOT use this axle again, if I ever have to rebuild the disc brakes, I'll probably adapt something else, IE Jeep? The parts for these brakes were only made 2-3 years
