80w90 gear oil.

something like castrol VMX80 works well, dont use anything expensive or you will be kicking yourself when it breaks and you throw the oil

I got curious so i checked the book, GM SPEC HN1046 SAE 80w/90. Being pretty old now chances are its a little worn so i would go the VMX 80 as suggested to help syncro operation, any of those oils would be fine, the quality of oil is a hell of a lot better now then what was a available in the 80's.

I have run VMX80 in Aussie 4 speeds sadly also waisted in it M76 5 speeds and it made even new boxes change much smoother. I built an aussie 4 speed that was a little notchy going into 2nd back from 3rd after changing to vmx it was perfectly smooth
