I'd like to replace the post sleeves in my TSPP to match the original Stern 545-5308-00 ones made from hard rubber, 90 durometer, but can only find 545-5308-00-65 made from 65 durometer. Does anyone know where you can buy a direct replacement? Marco is out of stock and the other US suppliers I checked combine both of the Stern part numbers into a single item so probably supply the softer ones. I'd like to keep the game playing as designed vs. creating more bounce with the softer posts.
