Looking for a nice set of 4:88 or 4:56 gears for 57-64 chevy rear. After looking at the 4:88 set I have, the pinion gears are too fractured to use. Gears have to be nice, no rust. The rust makes them noisy no matter what you do. Would also consider an complete open rear with the gears, same deal though, the gears have to be nice.
