Same part numbers for TM125K and RM100A
except third as it has an upgraded part number but is essentially the same unit.

Probably find RM125 wont be too different either.

the thing to do is ditch the TM clutch in favor of the RM straight cut version - big difference for the engine. If you have the bits consign the TM clutch to shelf stock....
