I received my damper today. I installed it using two  8mm x 1.25 Pitch x 40mm long S/S hex bolts. I used 13mm high nylon spacer on the bottom and 3-4mm nylon spacer on top. It works great and you can go from not even feeling it to having hydraulic pedals.  This is a highly recommended  modification for all that have the Crosswind pedals.
