There is a plug at the far end of the steering box Shop Manual page 208 top left had corner.
Is this a freeze plug or some other type of plug?

If it's the same as a 35 it's a plug you can take out and inset a grease zerk to add grease.

The "plug" for adding lubricant is a pipe plug with a suqare end.
The factory does not recommend adding a grease fitting for fear the steering box can becomed over filled and grease working its way up the column. Also chassis grease should not be used as it will not flow into the bushings and bearings.
I mix chassis grease with trans. gear oil to get a medium mix and it can be slowly poured in.

Jon,
Thank you for your reply.
I am referring to the plug that is about 1 1/4" that is at the end of the steering housing (Group 6.785) in the master parts cat.
There is also another picture of it on page 207 of the repair manual, it is either convex or concave.
Hope this of help.

The steering worm shaft passes through that opening when it is installed or removed.

If your plug is gone you can likely find a soft plug the correct size. Mine was gone and we found one to fit.

Do you remember where you got it, if the plug was brass or steel and how thick it was.
Thank you for your help.

You can pick one up at your local auto part store. They are soft steel.

Steering Gear Lubrication
Mineral oil with 4% to 6% soap
What do you make of that?

At the rate they wore out I would say it is bad advise.
In the later years GM sold a steering box grease that was just thin enough to flow into the tight fitting parts.

I use Penrite Steering Box lube in my cars. Basically it is slumping grease.

So do I. It's great stuff. It stays in the steering box. Heavy gear oil just ran out on the ground.

I am using John Deere Corn Head Grease (AN102562)in the steering gearbox on my '37 Master coupe. It is a NGLI #0 self leveling grease. Other ag machinery companies and co-ops such as Cenex sell it.
This type grease has reduced viscosity when load is applied to it such as between the teeth on the worm and sector. That means it will flow between the surfaces and provide lubrication.
The real advantage is that the viscosity will be greater away from the load areas so it will not leak out between the shaft and bushing.
