I bought some GL-5 85-140 to refill the differential in the 37 with.

But I have had no luck locating GL-1 90 in quarts for the transmission. This is what Ross had recommended in one of his postings.

I see that NAPA sells it in gallons, but I think that would last a lifetime and a half. Does anyone sell it in quarts?

They sell the below on Amazon. 1 Liter

Thanks!

Check Lubriplate site. They have a dealer locator. Number 4 gear oil is non-EP 90 weight.

90 weight gear oil is ISO 150 in case you need that number.

They show mail order dealers as well in case you don't want to use junkazon.
