Thanks Andy, Roy. Yeah, looks very neat, but you can imagine everyone in the F250 championship saying 'you're a cheat'.... even though it was still and NSR but with the RS dry clutch/gearbox fitted.

So I want to play safe (and fair?) and just fit the gearbox internals in my NSR.

I'll keep looking for an F3 gearbox then. Thanks for your help.
