Hello, I have a 1951 Willy's PickUp truck with the original transmission, rear end (Timken Clamshell) and a factory Warn Manual Overdrive BUT the front end is out of a 1986 Chevy S-10 (Steering Column, Front end and V6 Vortec engine).

My question is gearing the rear end to get a higher speed, currently I get 55-60 MAX but I feel more comfortable at 50mph. I would like to improve the gearing to be able to drive it on the highway, 60-65mph.

Any suggestions are greatly appreciated!
