Beautiful work. Don't know if I would have the ambition to start over and completely scratch build a chassis, but you make it look easy.
Is you engine Centered? All of the cars I have checked, including Cobras, the engine is usually centered 3/4" or so toward the passenger side of the chassis. I'm not sure why, but I have heard several explanations running from counteracting engine torque rotation to making more room for the driver's foot box.
Keep up the good work.
