So i am rebuilding an a #385 and noticed metal pieces were fixed on the center of both front and rear trucks. I have since discovered how important they are as the trucks do not seem to stay on the tracks without them! In the picture however you will see that a "makeshift" spring was made by cutting a saw blade (on the left.). Are there replacements for these? I am having trouble locating them as I can not even find a part number.
Thanks in advance for your advice.
