Quoted from cottonm4:. But you are in for near $100.00 by the time you add in shipping. And this one does not have the three angle/border brackets that go around the door. If you do not have those angle brackets you will definitely want them and a lot of door sellers don't think about selling them with the door.
I've looked at the Ebay ones, those are all for arcades. They don't have the lockout assembly from what I could tell. I'm missing a few parts off a couple of my games as well, it's annoying because I actually put mine on location. It's a pain in the butt to find the stern coin door specific parts.
Finding a full intact stern coin door isn't the easiest thing to do either, I was able to find a Chicago coin door for 40 bucks and steal parts off of it.
