I do have a few concerns, esp if we were to bolt our harnesses to this bar. The plate that the main flange is bolted to is the same GM composite/plastic. Underneat that is a flimsy, maybe 2mm thick bracket. The composite piece is sturdy and sounds solid when you knock on it but those break real easily. The firewall is pretty thick though. Have you guys though about extending the center towards the firewall so you can bolt it to something with better structural rigidity?
