Jack, forgive me if I missed it but could you or have you described anything about the firewall treatment where the master cylinder and clutch master are mounted? Is that a product available in the aftermarket or a one-off fabrication piece?
The bracket is available from DSE and thru Rick's Camaro for $29.95. The bracket can be either welded or bolted to the firewall.
