I have a nearly new set of Richmond gears with a Richmond spool to fit a 10 bolt Chevy rear end. Ready to bolt in. The are all set up on the carrier to include bearings and yoke. Gear ratio is 5:57 and they were used for a short time in my Camaro for Circle track racing. Have many other racing parts as well like, Corvette flywheels, racing leaf springs, racing wheels, Chevy heads, racing radios. Will be posting more ads for the rest of the parts once I get pictures.
