I bought the Dana 60 on Ebay for $1,650.00 plus freight, total $2,000.00. It is 48" axle to axle so I am a bit concerned about fit.. I put in AMD 3 1/2" wider tubs and relocated my springs to be in line with frame instead of offset. Since the backing plates are too close to the frame, I have to go with rear disc brakes. Any ideas?
