Firewall Flex 67-67 F Body

I've seen Chevy II racers make a brace that runs from the master cylinder to the top of the shock tower. Theres quite a bit of movement on those cars,,up to 1/2 an inch with the old heavy clutches we used to run back in the '70s,,,maybe its better with the modern clutches.

My guess is you have old 2800-3200 lbs. pressure plate? If so take it out get a good clutch setup that will fix your firewall flex and save every driveline piece in the car.
