    Quick question, I have a 1986 G20 that I have been using as a parts truck. I have removed all the running gear except the rear, is It worth my time to swap it with my C 10 Silverado?

    Just a 10 bolt corporate axle right? Nope. If it's an 8-lug axle it could be worth saving, but it's not a direct swap into a truck. The perch spacing is different and the housing is wider than trucks as well.

    It’s a 5 lug rear, just was wondering if it was the same as the one in the 1/2 ton trucks
