do you remember if was the engine was mounted longitudinal or transverse?Hello Lee.
Yes, I know Rex, he ran his "McLaren M6B" replica at Bonneville a few years ago and did 200 mph. He also competes in the Nevada open road event "Silver State Classic". I did ask him about what rear uprights he used and he said that he had fabricated them. I don't remember much more about his car but I'll post a few photos for you.
No, the doors on my car were not an option. I decided that if I needed to exit the car quickly (on fire, etc) the stock two-piece door arrangement was too complicated so I bonded both upper and lower doors together.
