2015 X-Carve, Adding Side Board, Parts Needed for Vertical Drag Chain

Having a heck of time trying to figure what parts I need to install the Side Board Kit onto a circa 2015 X-Carve. Specifically all the parts needed to make the side Drag Chain go from horizontal to vertical. I have placed three separate orders now and worry I still am missing something. For example, the instructions show this part but I am not sure if it comes with the upgrade kit or not. ALso doesn’t seem listed in the discussion threads.

Any definitive list of what is needed to successfully install the Side Board Kit onto a 2015 X-Carve?
