I just came over from the Chevytalk web-site with a question about the available axle ratio's in 1957 for Pontiac. I have a complete 57 Pontiac axle under my 57 Chev and was wondering what ratio's were available. I'm guessing mine is about a 3:08 or so by turning the wheels and counting the pinion. Is this close or am I way off base? Thanks in advance
