My mother has a 81 stepside GMC 350 350 trans.
She was involved in an accident and bent the housing on the rear end. They replaced it with a used one. It had a pretty high road gear that I am not sure of the ratio. They replaced it with a 3.73. The truck still has stock tires that I think are 265/70R/15's. Does anyone know what speedo gears go in it for this set up?
