I have a 1933 pontiac. Its been in the family 50+ years. I am getting ready to refurbish it for the 3rd time. I used to have information regarding three different ratios for the ring and pinion gears. They were listed simpley as the hill,standard, and plains models. The markings say 467 9-90 2-33n on mine. I have lost most of the info we had accumulated through the years. Hollander also lists some chevy's with interchangeable rears. At one time we had a chevy rear in it but it snapped axles easily. Also I am looking for a front Trunion(u-joint) for a 34 pontiac. I have been out of the Old Car hobby for a long time and would appreciate any info I can find.
