Scott, this info is dated and may not help, but just in case:
Here is his contact info. (he is a member of the Ferguson Enthusiast of N. America)
Albert (Al) Hoyt
(352) 568-8166
Box 396
Center Hill, FL 33514
He has the wooden bearings (aka bushings) for a Ferguson ABO-21 disc that he bought in bulk.
Ferguson part # ABO-5580-B (bottom) and ABO-5581-B (top)
They are identical to the bearings in the Dearborn disc harrow.
