You're welcome, Tom. BTW, I pulled the side off my steering box and scraped out as much of the old crude/dried oil/grease as was possible. Then I sort of cleaned out the box by spraying WD40 in and a small model paint brush to clean further.
After putting the side of the box back on, I used a plastic oral syringe from the local drug store to squirt the Corn Head grease into the steering box through the zerk fitting hole.
After a few drives to let the grease settle, I took out the zerk fitting and squirted some more Corn Head grease into the box.
Now I don't worry about it.

Cheers, Dean
