Nick, My brake master cylinder has the same casting number as yours. My brake light switch is mounted to the floor board under the brake pedal bracket in the engine compartment. That little adapter that Dan pointed out might work for your situation. Also, I believe my brake line fittings are 7/16 x 24.
