How do you identify a Dana 60 Rear End? I have a 1970 GMC C20 long bed with leaf springs in the rear. It has a 10 Bolt rear end. It is a Full Floater with 12" Drums. The Drums just SLIDE OFF, the Axles do not need to be removed to take off the Drums. It has 7 bolts attaching the Backing Plate to the Axle Housing. It is 8 Lug with 1/2" x20 Wheel Studs. Looking at the diff cover, on the passenger side, it has a code written upside-down C-30255, and below that it has the number 60. Is this a Dana 60 Rear End?
