Can the effort reduction kit be replaced with the pedal box in the car. My car has the factory installed kit and there is a little slop in the pivots. Looking up under the dash it seems possible if the shaft that the gas pedal and bell crank pivot on will slide out. Does anyone know if that shaft slips out or of it is pressed in? Before I go to the trouble of trying to get it apart I’d like to know if it’s possible. I tried prying on it a little but it didn’t move.
