As Dave said, the left side rocker panel Fiero assembly will fit, as well as the similar Porsche 914 mechanism. What's needed for this is a handbrake lever that engages, locks then allows the handle to relax flat so it's not impossible to get out of the car with the handbrake on. I always thought a Ford pickup foot-brake pedal could be adapted to a Pantera over the missing dead pedal area, but I've never seen this done. Safety features don't get the attention that monster power does.
