Dually with 4x4?
 

Hi all! I have a 76 F350 dually (Clevo, ZF 5 speed, and Dana 70), and I'm looking at putting a front diff in it (Dana 60). Just wondering, has anyone ever done this before, not so much worried about the chassis mounts etc, more so fitting my dually alcoa rims on the front....? (Trying to avoid having to re-invent the wheel, but I will if I have to.....):) Thanks!
