I have a 67 GTA fastback S code that was built Sept 66.The brake lines were not installed when I got the car so I am trying to figure out how they all hooked up.The proportioning valve was still mounted on the car to the floorboard just forward of the drivers seat.I am seeing there are 2 different style line kits for pre 2/67 and post.I got the pre 2/67 but they dont seem to line up with the proportioning valve location.I read about the valve at the rear axle and under the hood but cant find anything for it being under the car.thanks
