Default who makes gl-4 trans oil 80W90?

Went to 5 places today looking for a true GL-4 trans oil.

Found a GL-1 for pre 1953 Ford Tractors.

Some bottles say GL-4, GL-5, which is fine for rear axle, but not a brass ring sychro trans.

Don't want a synthetic. Just good old fashioned GL-4 suitable for a vintage trans.
