Kansasracer - you start by removing the Associated/Yokomo dampener post. Then insert the Paragon post till the threads bottom out, using the nut to lock the threads on top of the standoff. Now install the threaded body on the post. Do not use a spring on the bottom. Install the dampening puck on the threaded body with o-ring as used on the other version. Place the top pod plate on top of the puck. Now install the top puck with o-ring. Put a spring on top of that, then install the threaded nut. This piece is rare so don't loose it. I cut a piece of fuel tubing and put on top of the nut so it won't spin off during racing. Be carefull here that the tubing does not touch the center post and restrict movement up and down. Now set the tension you want. You can use different thicknesses of lub or dampener suryp on the pucks to get varying degrees of dampening. Good luck and good racing.
