Has anyone else with a '67 390GT Mustang built at the San Jose plant notice any fire wall markings in wax pencil?
I have a 1967 390 GTA coupe and during it's restoration, I noticed that there were some firewall markings in wax pencil. I have spoken to many people about these markings and they have been noted on other big block equipped San Jose built cars, yet nobody knows what they mean. If anyone out there has the answer... you are truely a Guru!
Thanks.
