Hey guys, I'm new here, and the new owner of a 68 GMC shortbed. The question I have for you is: Mine has a 10 bolt rear end, and I was wondering why? Aren't most 12 bolt? What rear end is this, assuming it's factory? I'm new to these trucks, but not to hot rods, so please be tolerant of my ignorance. I'm looking into installing a "posi" unit, and can't find this rear listed in any JEG's or Summit mags. Kind of looks like a Dana 44.
Thanks, Scott
