Just make sure you follow lucky rule #13...
13. CLUTCH MASTER CYLINDER: The clutch master cylinder must remain stock, within the stock dimensions, location and configurations as currently delivered by U.S. Legend Cars International. The clutch master cylinder and reservoir must remain on the engine side of the firewall. No aftermarket clutch master cylinders are permitted. The clutch pedal may be shortened for driver comfort.
I'm sure most tech inspectors don't worry about that, but after witnessing tech at Nationals for the first time, I'd be leary of anything non stock appearing if going to a National event
