GM gear sets probably came from 409 or Corvette applications if they were used, the book below references gear sets sourced from Pontiacs. The book I have was printed in period (circa 1964) that was authored by Bill Carrol. There are gear ratios referenced in this book also.
I have an early cast iron T10 that belongs to a 20XX Cobra that I am restoring, maybe I'll pull the side cover and check the ratios.
