It looks like you have the GM corporate HO33 which was later called the HO35. There were only two gearsets available for these. The GM 3747808 which is a 3.90 and later the 3764960 was available for auto trans at 3.38. I would be interested in seeing what you bought and what you are going to do with it. | | |
