Hello Bill,
I know it is kind of pricey, but Amsoil's GL-4 Manual Transmission & 
Transaxle Gear Lube 75W-90, product code MTG, is excellent for the 
shared transmission/differential of manual transmission Corvairs.  If 
your car has a Powerglide, then any GL-5 lube will work fine in the 
differential only.
Look up your local Amsoil dealer or go to online to find the nearest 
dealer to you.  I bet one of them nearby has this in stock.
