With the firewall not being available for mounting, and the body overhang on the GT-R being rather significant in going past the firewall, I wanted the coolant header tank to be mounted as high as possible and to be accessible. The lateral frame rail seemed to be an obvious mounting location. I added an "L" bracket to allow me to get the mounting as high as possible. It looks a little lonesome there by itself, but I will be making some additions to this area to give it a more finished look. Also, the mounting brackets need to be finished off with steel wool and protectant.
