I have looked before and I honestly don't think you'll be able to find any. For a few reasons, it's a Gottlieb, which means the rights are a pain, it's a low production game, and it's not very sought after.

Don't get me wrong, I think it's a great game, but most don't.

It's a Gottlieb, so the only one who has rights to make reproduction parts is found here: http://www.pbresource.com/index.html

Navigating that site is awful and it is difficult to try and find what you need. It's straight out of the 90s.

They do make sure to pursue anyone who tries to violate those rights too, which is why you're in a pickle.

Good luck!
