Thanks much David !
One small addition to finish of the interior panels , courtesy lamps on either side for the rear seat . I think they should be further forward on the panel so I'll end up moving them . I remember us kids sleeping on long trips and those lamps were bright enough to wake us up !
There were no door lock knobs on these cars . The door handle on the arm rest is pushed forward to lock the doors , pulled back to unlock , and pulled back all the way to open the door !
