Thanks Rodger. I had always thought that was the case given how thin a firewall really is. I just wasn't sure.
The firewall is quite thin but we purposely landed the joint up high on the firewall to use the strength the kick panel floor vents create. So there is a really strong section these massive joints weld to on both sides of the firewall. granted it is no where near what a 10-12 point cage would be. But this car will be driven 99.9 percent of the time with out a helmet and if you have not heard me soap box session about rollcages in street cars, I will save you. Its on here quite a few times.
