Cork, using my unreliable memory, I installed the tour pak/mounting bracket/docking kit last November when I got the bike. I have forgotten the torx number that is required to remove the 2 bolts on each side. There is nothing magical about the process. It is just a long bolt you remove, then add the 2 wider spacers to each side and put in the longer bolt that should have come with the kit. the reason you need the docking kit of course is because without the wider spacers you can not install the saddlebags afterwards. That is the only reason. When I get home this evening, I will investigate it just a little more and try to get you some more detailed info. But it is one of those torx sizes you mentioned, I believe. Now, if you need to remove the rear footpegs because you want to add rear footboards, you will need to purchase longer torx drivers that are available at a Shuck's store for about $16 for a set of 4 larges sizes because the bolt is in there too deeply. But that is another issue.
