Hi,
I just bought a 79 Chevy C-10. It has a 250 inline 6 and a 12 bolt rear. How do I tell if I have a posi? Also how can I figure out what gears I have. I also have a 12 bolt rear that came in my 76 C-10. The 76 is currently undergoing a full frame off resto. How can I tell if the rear on that is a posi, and the gear ratio? It is currently sitting on jackstands in the garage. ( the rear axle)
Thanks for your help!!!
