ID a rear end

[drewcrew]

I've got a 1991 C-1500 rcsb. A few months ago I did a flip-kit and noticed there are 2 sets of spring saddles welded to the housing ( 2 on each side ). Is there anyway to find out what it came out of ? Serial numbers, part numbers or stampings that might help. IF there is a number that will help where would I get the info to decipher it ? Thanks.

Are you certain it has two sets of saddles, and not one pair of saddles, and a flat area that contacts the bump stops under the frame?
