You are correct Alex. There are several specialty oils with EP additive packs that are yellow metal "friendly".

Les: I have decided to use Royal Purple MaxGear 75w90. It is available through Canadian Tire.

Below is some info from their website:
Max Gear is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe.
