I'm not sure Real 1. I do know that there is extra bracing through out car. It has 3 bars on sides behind door and was told extra bracing behind dash. The car can be supported by quick jacks because of extra bracing. All the rest of factory approved full competition cars I have seen have same dash. I shared parking spot with owners of csx1003 , which is full comp car also, at SAAC 35. It has same dash. Shelby gave Finishline Motorsports ok to build 22 cars but only 12 were finished, of which csx4163 is number 7. Finishline
motorsports built the Shelby Challenge Racers also, and they share same reinforcement less large roll bar. I thought about changing some things but decided not to, it is what it is. I love the look of your car as well. Sorry but I have to say more info page 711 and page 780 (:-) lol. Don't take the wrong way , I would like to know also.
