I have to admit the flippers on Vampire do need a upgrade. The bonus shot has to be just perfect with factory flippers. Any details (part numbers) on the parts you changed. As I mentioned I currently don't have the game in my position. Maybe someone has a previous post on upgrading Bally flippers. I'll look but i'm not very good at searching Pinside. Anyone have pictures before and after the upgrade? I'm going to use pinballplatingandmore.com for my metal work. I meet him at Allentown and again at the Atlanta show. Great guy.
