Great project. I'm preparing to do a playfield swap on my Fire. Only issue I haven't licked are the buildings on the right. My clear bridge broke off the building and has a good structural repair, but can be seen. You mentioned plastic repair, are you talking about the buildings or just the regular playfield plastics? The playfield plastic sets are still available, but the buildings are not and if you have a method for repair I would really like to learn how it's done.
Best of luck and enjoy.
