The kit even has the bubble in the roof. If I remember it was to accomodate the tall driver (Dan Gurney, I think). I was out at the Ford Racing School in Tooele UT last month. I drove a GT350 one day and a Boss the second day. Life is good. Nice job on the GT40. I spent days painting the metal rings on the seats by hand. Phew! It is a really nice kit and you did it up right. If I remember correctly Revell also did a kit of one of the winning cars.
