I have the 4 pt. docking system on my 2010 RKC and have an HD backrest and an HD luggage rack. Both the chrome spool and the black spool are used when you mount both accessories. The front of my backrest frame uses the inside shock mount and the rear uses one of the double spools (can't remember if its the chrome or black one and the bikes off site in storage or I would take a pic for 'ya). My luggage rack uses the remaining front spool and the rear one. Hope this makes sense to you.
As a note, if the backrest or rack mounting plates are even slightly off kilter/alignment, it will be a p.i.t.a. to mount (not much wiggle room or slop). I had to bend my brand new backrest at the mounting plate out ever so slightly so it would drop in.
I have them on my 2010 RKC with no problem. I am sure you will figure them out by looking on Youtube from dbmg.
Hoping Bill got this figured out?
