I may be wrong on your truck, now that I see it is a 46 older body style than I was thinking of. Seems the trans then was some diff and non-sychro. You may want to use the later 48 to 66 SM420 trans to do that. You also may not have parking brake on trans, and not sure if they had Hydro-vac brakes back them either, Sorry! :o
