John,
May also be a good idea to pick up a few of the pins that hold the door guides in. They are small and get lost easily. They can be removed by carefully heating the head with a soldering iron and immediately pulling out with a needlenose pliers. Attaching them is a reverse process. Push them in manually as far as they will go and then apply heat and push in with any object. Later boxcar production used tabs on the end of the door guides that fit thru the hole and were bent over to secure the guide.
