Finally, someone I can help, usually I'm asking for help.

Jeg's and Summit are selling new gears I think made by Motive
Gear, who owns Richmond. I got them dropped shipped from
Midwest Truck and Auto, big distributorship in Chicago.

I don't think they have every gear yet for every ratio, but
I got gears for my ROD-6, which has some gears in common
with the 5-spd.

Get the gear part numbers from the Richmond website and type
it into Jeg's or Summit.
