hello everyone, i have a couple of restoration projects going at the moment and need a little help.. i have a optima, turbo optima, ultima sideways and a original ultima.. my question is what is the pinion i need for these.. the manual says a 15tooth but no mention of the pitch..??
i'm also in need of the very expensive spur/centre gear.. are there any other options to replace this gear?? no one making repro parts of these yet???
cheers

Pitch is 32, and unfortunately no aftermarket currently for the counter gear. One member has modified his motor plate to fit the traxxas cluster gear but it's a different ratio- not sure how it would work for you. Also not sure the gear cover still fits

thanks for the reply, time to start buying more parts..
quick question tho.... what is the difference between the 3 hole and 6 hole spur/counter gear version 1 and version 2???

definately keen on the traxxis gear, have a modified set of optima plates that i wont use in a resto so might have a play...
