Finding one of those 4.10 gearsets is about like searching for a chicken with lips! A lot of them got installed (and worn out) in dirt track race cars in the late 1970's. They were just right to run against a Muncie 4 speed in 2nd. gear on 1/4 mile tracks. They made the engines run 3K RPM in the turns, and 7K at the end of the straights! We scavenged up every one we could find in all the salvage yards back then.
