2wd differential oil type?

Toy book says 80w-90 or 85w-90 for 0 degree F or below. Straight 90 wt for above 0 degree. Here in central Fl, its never below 40 F and never below 60 when I drive. Typically 75 tp 95 F. However, I cant find straight 90 wt anywhere. All that I can find is 80w-90. Is that ok? Also, its carquest brand. It is API service GL-5 which is what toy calls for. OK to use? This will be my 1st and maybe only diff oil change. I do want this vehicle to last forever.

If you haven't already tried it, I would suggest looking somewhere that sells supplies for commercial trucks. One of many things you will probably find is the heavy gear oil you're looking for. If you can't find the straight 90w, 85w-90 should be fine. 80w-90 seems a bit light for your climate.
