Finally a firewall brace kit that works. This sturdy kit contains a clutch master cylinder bracket, adjustable tension rod and bracket to attach to "existing" strut bar mount. Mount bracket to clutch master cylinder and strut brace mount and then pre-load tensioner for best prevention of firewall flex due to stiff pressure plate.
Note: Firewall brace kit does not include Strut Brace Mount. If you don't have a strut brace, I can make a mount similar to picture for $49.00
