Joel, it appears the "Bracket AM30183" you need is no longer available from JD. Neither is the subbed kit number AM30567. The wire and conduit have a price, so appear available but for $48 plus. You could do better!
Knob still shows for $5.53.
Anyway, put a request in the Classifieds here for a good used one. The 112 RF and RF 110 share the same bracket. Look them up on JD Parts under "Levers" to be sure so I don't lead you on a wild goose chase. Good luck with the search.
