You could just count them.

You can just count the teeth, and divide the ring by the pinion, to be SURE. But as said above, 4.30s.
An excellent ratio for a small block 1/4 car, or a big block 1/8 mile.

Good score,4.30's are no longer available. I ran them in a Dart for years.It was a good match for my combo at the time.

Thank you!! The whole rear end was in amazing shape for a car which sat for years.
