My Cobra had top mounted pedals attached to reinforced fiberglass. The master cylinders were mounted to the fiberglass front wall of the footwell and they were also reinforced. I installed Tilton floor mounted pedals in my Cheetah and had to reinforce the sheet metal floor to keep it from flexing under application of the brake pedal. ... My point is that the mounting surface(s) must be strong as well as conveniently located. That may shape your decision.
