These are retained by an M6 bolt, nut, washer, and a short piece of rubber fuel line that expands when the bolt is tightened. The idea of the cap is to allow fine adjustment of the height with washers between the cap and spacer. You want the seat base to just contact the cap. You can see this by looking from the side. I also added a short M6 screw, nut as a locknut, and .5" cap to the top of the coupler nut that retains the brace or original batt box. This is also adjusted to just contact the side of the seat base. The idea is to provide support to the sides of the seat, preventing that flex and rolling feeling when you shift your weight to the side.

The result is a 100% improvement and elimination of that cheap feel to the seat.

If you have access to a shop there are many ways to do this. These parts allow a quick off the shelf solution.

My seat fix support is not nearly as fancy looking as yours. But it is now 10 times better then that plastic battery box that was compressed and starting to crack. Thanks for your idea I was able to modify mine.
On a side note - In order to save my marriage I am no longer going to do any more mod's to my bike...... ;-)
