Does any know of anyone who is making, or has a work around replacement, for the vibration damper/shock absorber that sits just below the powerhead on a 4404 Zephyr? Its the one that is made up of 12 round balls [rubber I would think] The ones I have look more like hard plastic and are in bad shape . If I can, while I have it apart I wold like to replace it. If I am seeing it correctly, I believe the part number is 200210 Thanks
