I just got some Sparco pedals and now realize i have a problem. My ZX3 is standard. I get the gas on and work through that problem my self(the cross section on the underside of the pedal doesnt allow the nut for the peal screw to center on the hole but im taking the gas pedal off and drilling away that later this week). The main problem is the clutch and brake pedal. The existing pedal plates are welded to the arms. I cannot drill through the center of the pedals because there is no way to get the nuts on, (the screw would go right through the middle of the arm, if you have a ZX3 take a look and you will notice its impossible to drill.) My only option i can see is to remove the whole pedal assembly and torch off the existing pedal plate and weld the Aluminum Sparco pedal right to the arm. It is also not possible to simply just offset the sparco pedal to the right or left to miss the arm on the back. This exposes the stock plate and looks real bad. Any sudgestions before i break out the cutting torch?
