Syd, despite the difficulties you've had, the GT40's progressing beautifully. I'm going to miss this thread when you and Cato are done! Fascinating amount of racing and car history here.
I've seen a GT40 race at Lime Rock Vintage (I've worked timing and scoring for that event) and they are surprisingly small. I have no idea what chassis #, but it's a darkish red with the #68 if you follow vintage racing. It's incredible how much safer the sports racers are today. I agree; crashing a GT40 at speed would likely have been fatal, as with a 917, etc. I'll never forget hearing on the radio that my childhood hero, Jim Clark, had died at Hockenheim. Back then, it seemed that every racing season issue of Road & Track I'd read listed at least one racing fatality. To drive those cars back then required the kind of fearlessness that one sees in extreme sports events today. WW1 pilots had the same mentality; how could you fly what was essentially a wood and fabric motorized kite, and have any real faith in it? (Guess that's why Eddie Rickenbacker was also a hero; he raced AND flew those things!) I think I'll pop my tape of the movie "Le Mans," or "In Car 956" in now!
