"NAPA sells the parts necessary to tighten up the gearbox.
I rather doubt the parts will cost much more than 75 bucks.
You need two sector shaft bushings: B7C-3576-A
new sector shaft seal: C7OZ-3591-A (replaces B6A-3591-A)
and housing gasket: 7RC-3581
two steering shaft bearings: 68-3571-A (Industry # 5BC)
and races (one each): B-3552 (Industry #6) & 8A-3553 (Industry #6CE)
That should do it. NAPA can cross these Ford part numbers over to the brands they sell. The Industry #'s are what autoparts stores go by for bearings, races, etc.
These same parts are the only parts replaced in rebuilt gearboxes sold by autoparts stores.
While your truck is a 1960 F100, the steering shaft bearings are the same from 1936 thru 1960, one steering shaft race was used 1932 thru 1960, the other race and the housing gasket are the same from 1948 thru 1960, the seal fits most 'everything from 1948 thru 1972, the sector shaft bushings from 1957 to 1960."

This is what I finally found this morning searching the forums. I am having a hard time cross referencing the parts over to N*pa parts numbers. I can't seem to find the interchange anywhere.
