Help!

I went to the parts store today to try and buy seals and cover gasket. Without knowing what type of rear end my truck has it seems there are two choices Dana or GM. Can someone tell me what rear end my truck has...without pictures! It is a 72 K 20 (3/4 ton 4wd) and the rear has a removable 3rd member or center section and also has a removable rear cover that is round. 8 lug floating bearing axle on leaf springs
