hey guys i am new to chevys. i picked one up cheap and i am ready to start building it up. it is a 79 k10 short bed with a 4" susp and a 3" body. the truck is pretty rough shape. it has a 12 bolt in the rear and a 10 bolt in the front. i know the 10 bolt will not last long, any suggestions on which one to swap it with? thanks
