Stock gear ratio in 1964 98

The diff carrier is stamped with a number on the outside flange where it bolts to the axle housing .
It will be in about the 7 o clock position as you look at it from the front.
The axle codes are listed in the 1964 Oldsmobile Shop Manual.
The letter "L" stamped next to the code number designates a limited slip (posi) differential.

3.23 is my favorite ratio for these old cars. Obviously 3.08 gets better mileage, but 3.23 is more fun. Recommend against 2.93 if you come across it, best mileage, but not so hot off the line.
And we’re not keeping these cars for their legendary fuel economy, so why not have some fun?
