3 point hitch on 3450

[Firesmith]

I have a friend who has a 3450 that he bought with a back-hoe on it. He wants to get all the parts to get the three point hitch working, lift arms, sway chains, ect. He has the rock shaft arms but nothing else. Is there a salvage yard for these tractors to get parts from, or is the dealer the only option? Thanks for any information.
