I bought a Dana 60 rear for only 100.00. The axle is a full posi and was said to have been from a 67-72 truck.
How can I verify this? I want to put this under my 1981 K5 Blazer.
I know I will need to weld new spring perches on it to fit my Blazer but thats no big deal, I just want it to be ALL chevy.

Thanks fellas in advance.
