Don, thanks for response to my diff needs. I did find a setout of a 1972 Blazer. The blazer. Was taken a one last beat through the bush a few years ago, just tearing them down now. The. Front. Diff did have a. Tag that. Said gears where. 3:73. Opened up the rear cover yesterday,water was in the rear, front pinion seal was leaking. Gears don't look bad, gonna see what shape the axle shafts are in, defiantly gonna purchase a posi unit for it. The guy I bought the diffs off has a 3:73 posi used for $150. Just don't want to buy used and have trouble. Thanks again.
