[/IMG]I have a differential carrier I am going to sell but I am having problems finding what it is for. Ok it has 10 bolts holding ring gear on ring gear has stampings 1382745 40 11 gmc v carrier is a 4 pinion unit with issue date 5/30/1961 looks like carrier number is 683030 but it is very hard to make out. It also is a two piece unit with bolts on the inside (closer to shafts) then the ring gear bolts. It also appears to take 28 spline shafts and is a non c clip unit. any help is greatly appreciated. thank you This unit came from a guy who has a 69 gs 400 . he had pro streeted it but he's not sure what it's from. <!-- / message -->
