A few years back, I was poking around here, calling people and generally doing research about building a GT40 kit based race car for the NASA enduros...eventually I went a different direction but still retain the Gulf paint job.
Have a few videos on the web from the in-car camera setup I recently purchased...thought I'd share. It's a shame that some of the "kid" in me is gone to where when I'm at the races I don't "pretend" I'm in a Porsche 908 or 917 or GT40 but when I watch the videos afterwards, I can see scenes from "The Speed Merchants" or "Le Mans" in there a bit.
