1977 rear axle ratios

Does anyone know what ID stamp was used for the "optional rear axle ratios" RPO #G95?

Mine shows OA 208 W7E1 Does that make sense?

Yes. You must have the L48 M20 4-speed. The 3.36 was standard with 3.08 optional so G95 on your car gave you the 3.08.

Close, L48 with Turbo hydra-Matic 350 (B7K26D) the invoice does not show the G95 as an option that came with the car, so I was curious.

OK, since you mentioned G95 I thought you had it.

With the L48 automatic there were no optional ratios, and all cars got the 3.08.

Well that cleared up that part! Thanks!
I've been looking for the build/tank sheet also, any other ideas where to look? I have not dropped the tank yet but I have dropped the spare tire rack and looked.
