Thanks.
But anyway, why don't you change the clutch completely to the Centax 3? That would eliminate the problem since you will use the Centax 3 flywheel and all their internals. Just make sure your engine mounting height is 14.5 mm with a 4 mm chassis.
Yep, I'd reckon on using all the Centax 3 bits, including flywheel, but I'm not expecting the 710 pinions would work with the MTX spurs and also thought the whole Centax 3 clutch might have been longer overall. Maybe because it's skinny, it looks longer.
Or better still change the car to a 710? 
But there's no perceivable advantage in this, though.
