After many years of service, my spider gears on the differential are beginning to chip. I am not aware of anyone making replacement gears. So, it looks as if I need to scout out the wrecking yards for good replacement gears. What range of years are interchangeable for spider gears on a 1956 Chevy ½ ton? My best guess is 1955-1962. Does anyone know if this correct?

I really do not want to do a rear end swap since the brakes, 3.38 ring and pinion and bearings are in excellent condition.
