Al, is your's a factory non-posi?

I haven't seen many.
According to factory production stats, they only built 2,632 without a posi rear.

SAE 80W-90 GL-5 gear oil. Brand is not important, just the SAE viscosity and API GL-spec.

The approximate capacity is 3.7 pints.

(Same oil for manual transmissions - about 2.5 pints for four-speeds.)

Postraction axles use the same oil, but need the friction modifier additive to prevent clutch chatter.
