Okay, back to the Dana 60.
Mine is a 3.54 Posi unit as well, but an 8-lug full floater. Andy drove his 'Burb home from Washington state to Ohio and thought the brakes might be okay, or at least driveable for a while.
Um....no.
Once I got the rear hung in there I took the brakes apart for a look, and everything was junk. The only thing save-able were the star wheels and the brake bars. The backing plates had deep, heavy grooves worn into them where the shoes ride. Never seen that before. I welded up them up and ground them off flat.
