Jerbear,
I had great help from this lady at Shell Canada.
She was able to give me the name and address of the closest shop to me that had ordered 80W90 GL4 gear oil from them recently. Very prompt at getting back to me also! She also advised that they would ship to the shop for me if they did not have what I was looking for.
Drop her a line and see what they have nearby!
