Dana 60
Before I put one of those truck Dana rears in my Barracuda I measured my original rear to figure out optimal wheel clearance. Instead of matching the width of my original rear. I ended up going a few inches narrower. I didn't relocate my springs or do any minitubbing. - But the change in rear end width meant I could center the widest tires that I could fit with the rims I'd chosen.
I didn't do any mods to the suspension other than urethane bushings and I did replace leaf springs based on the ride height that I wanted. - Oh I did have to find another set of U-bolts and U-bolt mounting plates to accommodate the larger diameter axle tubes and I did make another driveshaft to mate the correct yokes and length.
