I am in lima ohio, we have a 1981 n-6 with a blown motor, hydro worked good, also has rear wheel assist. asking 4500.00 for complete machine. if interested e-mail kingbros@watchtv.net I can send pictures.
There's a guy in Kensington, KS, that was trying to sell a bunch of N6 parts last year. Try 785-476-2407 and ask for Don. I know he had a hydro sitting on the floor. I don't think he'd hold you up, either.
