Top Air Cleaner Hose

I have a 1950 TO-20, and two TO-30’s. Do you know where I can get the top part of the air cleaner that attaches from the filter unit to the screen on the dash?

The hose that connects the screened inlet on the dash to the top of the air cleaner, Ferguson part #180362M1, is a reproduction part available from after-market suppliers like Steiner Tractor Parts. Steiner sells it as part number MFS2247 for $16.95.
