Version 6 Gearbox Unique Parts

[strewthirwin]

Hi, I am buying a TM P90 second hand and am wondering where i can buy parts for it as some parts may be worn, i do know that primarily it uses V2/3 parts, however the tapet plate, anti reversal latch* and the gear which pulls back the tapet plate (sorry i dont know the name) are unique to the V6 gearbox, i aws wondering where i could buy these pieces.

Many Thanks

*I think it is called an anti reversal latch, correct me if i am wrong
