Rivarossi Big Boy

Wanted: gears for a 1968 Rivarossi Big Boy. The gears on the drive wheels are worn and I need a new set. Help please!

Golf Manor Hobbies in Cinn Ohio is the only Authorizied Riv Repair Dealer. Perhaps Ray, their part-time mechanic can help. See their dealer ad in in MR, 513-351-3849.
I also have a private source should GMH not be able to help. Let me know.
