Pulled the axles & third member out to see what was in there. I knew it had the better of the 8 3/4" third member, the 742 case which from Mopar comes with a clutch type sure grip unit but could have been a peg leg & someone added a sure grip. Lukily it turned out to be the stock 742 clutch type & it looks all fresh & rebuilt & I checked it with a dial indicator & it's good. I did the initial count of the tire rev vs driveline revs & thought it was 4.10:1 & that's exactly what it turned out to be.



Put the rear end back together & it's ready to go. The thing is super clean underneath, not sure what they painted it with but it's a glossy black from below the firewall back to the rear valance.
