Like so many others, my kids/wife/dog disposed of essential parts to the Whispbar system when I wasn't looking- I definitely didn't just lose them because I'm disorganized. In any case, the rubbery feet are what I need, from the K704 kit, pre-2015 models.
If no one has an extra set, I'd also be happy to get dimensions (really just need the height of the two ends) and print my own on a 3d printer.
