I am going to buy a C10 converted to a K10 here in a couple hours. It has a Dana 44 up front and a GM 14 bolt (the big one with a 10-1/2" ring gear) out back. I am sure there are a multitude of gear ratios available for both axles, but is there a way to logically conclude what ratio they are? For instance Dana44 has ratios A,B,C and GM14 bolt has C,D,E,F, then we could conclude the truck has ratio "C".
