Got some of the door parts together to get the interior mechanism started. I found the middle pushrods that are now included in the kit. This will make fabricating the aft pushrod much more easy as you no longer need to drill and notch the aft pushrod. Just cut it to the proper length and tap the cut end to accept the the new beveled end pieces. The first step was to mark a spot on the bottom edge of the door and drill a 1/2 inch hole for the gear box. The instructions have you cut a notch in the bottom edge of the door, but I believe that this is for retro installations. Since I haven't bonded the door halves together I plan to just drill the hole and go to the next step. I have seen other builders mention this. I can't see this part ever being removed as the pushrod ends attached to the rack gears isn't accessible when everything is in place.
