Paul - glad to hear more about the car - sounds wonderful! SAE90 gear oil is much too thin for the crashbox trans, not enough viscosity to suppress the gear spin. I'd use just what Packard recommended for years, plain old GL-1 (no additives, straight mineral oil) SAE140 or 160. Both are quite readily available though usually only in 5 gallon cans. Between the trans and steering gear box, you'll probably use at least a gallon for 1 change.
If your grease fittings are the old fashioned "pin alemite" with the cross pin, MSC in Harrisburg still sells an adapter to fit those fittings and allow greasing with a modern hydraulic alemite gun. That way you can keep the authenticity and still so easy grease jobs. If you need a picture of the adapter or the part number to buy it, just let me know.

EDIT - Paul, don't know if this is what you need, but it's still manufactured by Alemite for the older pin-type Alemite fittings. The threaded end swivels and attaches to the flex hose on your grease gun. The corkscrew end engages the pins on the fittings (which are also still available new) and in 1/4 turn it tightens down, depresses the ball check valve in the grease fitting, and grease away.
