This forum my last hope?

If I need to, and if they're available, I can order pinons in 0.58 and 0.63 modulus.

Again, many thanks,

The Duratrax Vendetta 1/18 RC car uses Mod 0.6 pinions if I remember correctly, but I believe the stock bore is 2.3mm. Might be worth a try looking at those

Brian's website shows that if the gear was originally 7.2 mm then the pitch would be mod 0.6. That's 48 pitch isn't it? I think that might be it.

Maybe look in the slot cars area?
