Here you can see Mark Houlahan (editor of one of our sister magazines) adjusting the position of the actuator. Once the position is set, it's very important to make sure the actuator is synched with the lock mechanism. Just like with the windows to check operation, use a couple of wires and a car battery to check the motion and operation of the lock actuator. If the locks work in reverse, all you have to do is reverse the red and the blue wires and the actuator will work normally. With our '57, the actuator was bumping against the door panel and causing the locks to trigger when the door was closed. The solution was just bending the bracket so it pushed the actuator away from the door panel. Just a simple bend using a vise was all it took.
