Anyone have a photo of the drain back lid spring? I saw it listed on the 519 parts diagram. There is a notch on the top of the lid "arm".

Any suggestions on where to purchase a 1.5" diameter black rubber ball to attach half of it to the bottom of the drain back lid? I reached out to Ron Scobie to see if he has one. I also reached out to the person in Iowa that reproduces the drain back fitter and it has the rubber stopper or seal. I have the deteriorated rubber stopper. I considered dipping it into the can of liquid rubber that is available at HD and Lowes.
