Here is the problem. I took out my D-60 to replace the bushings with the HD ORD Greasable ones. I figured i would rebuild the springpack while i was at it to get rid of all the rust. After i cut off the head of the centering bolt and removed the shim it fell apart. "Crappy Cast Aluminium" Since the axle is out and the spring packs are apart, i can not measure what the shim angle should be. Does anyone know what it should be. 1987 Chevy Longbed, Dana 60 Front with 6" Skyjacker (I think) not sure of the brand. Axle has not been relocated forward or back.
