Had to rework bracket holes to match firewall. Had to cut a vertical slot in the firewall to accommodate linkage to pedal arm. That rendered the boot worthless. Had to grind the end of the pedal linkage to allow for the brake light switch to mount onto the pedal arm pin. Far from "plug and play"! Get back to me if you would like suggestions.
