Many small salvage yards don't have a defined computer breakdown of parts that can be searched or participate in programs that are internet connected.. You have to call each individually with your needs. Several salvage yards with this model listed.
/ Looking for an upper PTO shaft for a Ford/New Holland 1920 Tractor
I don't know exactly your part but the New Holland CNH parts store doesn't have a reference for the part number you listed. Their site will list other tractors it's used on. Knowing all models will allow a wider used parts search.
