vwnate1: I am not as stupid as I look.
80w90, 80w, and 90w are known amongst the farmers and mechanics of my area as "Gearbox Grease". Go into ANY FLAPS or Tractor/Implement supply store in northwest lower Michigan and ask for "Gearbox Grease" and they will take you right over to the area where they keep the Hypoid Lubricants.
Also: Steering boxes do not use 90w Hypoid. There was a lubricant of much higher viscosity that was widely available back then that is not so widely available now.
The only place that I know of to get it is Penrite Oil. The product is called "Steering Box Lube" and is for use in "veteran" steering boxes. They do not recommend using it in Rack and pinion setups. It is found at www.classicautolubes.com
. Several 'bolters swear by it, and it costs about $12 (which includes shipping) for half a liter.
I have heard that John Deere makes a steering box lubricant that is the proper weight, but I don't know what the model number is.
