replacement gears

Does anyone know where replacement mating gears for the chiaphua motor can be bought? Where can we buy gears with a 25 degree pressure angle and a diametral pitch of 36?? Thanks for your help!

you can buy the motor assembly including motor, cluster gear and other stuff for 237 directly from atwood. I also think a full jack costs 247 or something like that.

As far as just the gears, you might have some trouble, they are far from standard.
