I found a rear axle assembly at a nearby large-format salvage yard that came out of a '67 chevy C20 pickup. It's been there in storage for a while and they had very little info on it. They told me it's a 10-bolt removable carrier and very large looking. I want to use the carrier in my 50 1-ton. What do I need to do to make sure it will fit. They're not open on the weekends and I can't get there during the week. They'l sell it complete for $100.00 and deliver it to the Chevy dealer where I work. Help!!! I've read a few posts on this, but I've not seen anything too conclusive. Thanks, Steve
