I installed a new torque box in my 69 mach1. everything looked good until i went to install the toe panel? It has a 1/2" gap between the torque box and panel. Im going to be pulling the box out again and fixing that problem. I believe something is twisted. My big question is does the flange on the frame where the floor touchs. go above the torque box or inside the box. I have no referance due to how the floors were previusly repair.
