As fare as Brake parts, Brakecylinders and Drumms I think I found the right parts for my rear end but the Part Dealer offers 2 different Diff. Seals (the one that points to the transmission) depending if it is a 1975 K20 1/2 Ton or a 1976 K20 1/2 Ton.
If I order it wrong, it's always a hussle
Again the Diff cast number is 3896839 N
12 Bolt/6Bolt rear end
Could someone help me?????
