Macsauto do have the actual seal I was talking about, 81T-3591, at $3.15 each.
Just found it in their catalog, along with the correct bearings and bearing cups for worm gear & sector shaft needle bearing!
Was in "V8 Ford Pickup 32-47" catalog.
Guess I better get the credit card out again
These are what I will order:
*81T-3591 Steering Sector Shaft Seal Retainer - Ford Truck Except 122 Inch Wheelbase
x1 $3.15
*B-3517 Upper Steering Column Rubber Bushing - Ford Commercial Truck
x1 $4.95
*81T-3571 Steering Worm Gear Bearing - Ford 2 Ton Truck Except 122 Inch Wheelbase Truck
x1 $8.80
*A14585S Wire Clip Set - On Frame - 1/2" X 1-3/4" Long - 10 Pieces - Ford
x1 $1.75 (for wiring along chassis)
*B-3593-A Steering Shim Gasket - .003" Thick Paper - Ford
x2 $1.90
*B-3593-C Steering Shim Gasket - .010" Thick Paper - Ford
x1 $0.95
Catalog - 1909-1927 Model T & TT - 2012-2013 Issue - USA
$0.00
Catalog - 1928-1931 Model A & AA - 2012-13 Issue - Foreign

Added 10/10/12: These parts have arrived today, and despite being the matching part numbers, both seal and bearing are most definately NOT THE CORRECT PARTS for the CMP. I will write to Macs when I can and discuss this with them. Do NOT purchase these parts in expectation of rebuilding the Ford 375 series steering box!!!!
