The lack of signs was pretty typical for so many home grown drag racers in the early to mid sixties before sponsors helped to "professionalize" drag racing. My '29 A/SR only had the shoe polish the strip folks put on it after tech inspection. That was in '67 and was still pretty typical for most home built race cars at rural drag strips.

Cool pic. In the day NHRA had some rules on how many mods you could do to the body in the Comp Coupe cl***. An old friend built a T coupe for the cl***. He set the national MPH record, I think at Alton may have been but had it pulled as they had narrowed the body. You could chop & section but not narrow. That's wen he pitched the T and went with a Topolino
