hi all i have recentley upgraded my jags gearboxes to high grade ones.
the original sprockets were a really tight fit and i had to drill the centres out to suit the bigger bolt suppled.
i now want metal sprockets but dont fancy drilling metal ones out does anyone know if tamiya ones will fit better?
please help
