Do you have a photo of the firewall pad used for '69 at San Jose ? so we can see the texture and try to replicate it.
Yes older thread but got an opportunity to shot some pictures of a 69 SJ Mach I yesterday that relates to this subject. Also wanted to demonstrate we don't give up and try to remember to look for details well after the threads have "passed on"
Mid March 69 projected build date - Same time period (approximately) as rockhouse66's car
