It could make unstable damper movement because 3/4 series's damper's screw thread is smaller than M3/M4 one. (12mm screw thread meets 14mm mount support hole)

So, it needs 12mm center hole to make it fit with 12mm damper screw thread. 28.8mm / 12mm / 3T Washer is one of choice to make it correct it's rigidness. Please refer to attached pictures. Thanks !
Quick question: on realoem.com the F30 bolt is a M12, the F80 is an M14, so that would indicate 12mm vs. 14mm holes, not 13mm vs. 14mm?

I'll try to find various washers see which could work and if it removes the slight clunking noise I got.
