Rear Axle Codes & Gear Ratios
Does anyone know where I can find the gear ratio for my 72 Cheyenne 1/2 Ton? I thought it was a 3:31, but now I'm not so sure. The rear axle code is: RHA 155 1. I have some Chevrolet by the Numbers books, but they are mainly for passenger cars and do not list that specific code.
Thanks, Larry

On the front of the axle tube (passenger side) near the carrier.
