Rod Shop

Geerhead55 · 03-31-2013, 01:57 AM

My only Rod Shop photos I could find were the 2 pit shots taken at Ontario Motor Speedway in '74 at the NHRA Supernationals, (the Dart photo has been posted before), and the 2 track shots taken at Seattle in '75 at the inaugural NHRA Fallnationals.
I'm not sure who the Challenger belonged to, but if I recall correctly, Dave Boertman came in and drove the car for that event.
