Doesn't really matter what tooth count.
I have to build a 26 tooth for mine, which means buying an older long shaft version and putting it on a later model short shaft version.
Doesn't need a good one, if someone has a worn or damaged one that would be fine so long as the shaft is still good.
Just hate to take out my perfectly fine (though inacurate) one and start heating it up and mess it up attempting to epoxy it in the new gear. Would rather start with a spare shaft, build my new one and have it ready when I take out stock one.

thanks for looking.
