1967 Turn Signal Switch help

[Tx67toro]

Does anyone know if the turn signal switch cam (the piece that actually pivots on the switch) can be purchased seperately? One of the locking tabs (that keep the signal on until you turn the wheel and it cancels) broke off and I need to replace it.
This turn signal switch is the "rare" one: Tilt/Tele Travel wheel with Cornering lights.
Any help would be appreciated.

thanks

fixed!
Got a replacement cam ($10) and installed into existing base. Works better than new.
