I might have some spare Tamiya pinions. I need a couple TRF F1 dampers. I also have the brand new Tamiya M-Type front wing & nose. PM me.
The stock spur is a metric pitch...depending on the kit it may have come with the 04 module (fine) or 06 module (more coarse) pitch spur. Often they are referred to as .4 and .6 pitch or metric 64 pitch and metric 48 pitch. Though caution should be used when referring to them as 48 or 64 pitch because normal pinions will not mesh properly with them.
