Yamaha CVP-50 Felt

Hi. Does anyone know if the felt sold for the CVP-70 (Part 1129) on Sytaur’s site is compatible with the CVP-50? I have a very nice CVP-50, and I have replaced the rubber strip and the master volume control, but the keys are “clunky” because of old, hard felt. I’d like to replace the felts…ideas?

Thanks so much.
