OK, here we go with some more questions about adding a quick detach tour pack to my 2008 Street Glide. For the purpose of this thread, let's assume I've decided to just order everything new so it perfectly matches the bike and enhances resale value as Smitty so wisely pointed out. Also, I didn't have a P&A Catalog in front of me so I was using a downloaded version. I'll try to walk through these assumptions and questions in order: 1) I already have a Sundowner seat on the bike so I'll have to use the two up mounting rack instead of the solo one. 2) I already had the detachable passenger backrest put on. According to the diagram on page 389, this backrest uses mounting positions 3 and 4. 3) The solo tour pack rack also uses positions 3 and 4 but I can't use this because of point 1 therefore 4) I'll have to add the docking hardware for positions 1 and 2 in order to use the two up mounting rack Follow me so far? What did I miss? The picture on page 389 shows all four mounting positions installed so I'm assuming this is not a problem. The other option would be to slip on a solo seat and then use the solo tour pack rack which would use the docking points already on my bike. Drawback to this is you lose the capability to bring along a passenger or use that passenger space for more luggage. I think I'll go with the two up option so I'm thinking I need to order the Tour Pack, Two Up Mounting Rack, Two Up Docking Hardware, and the Backrest to put on the pack. Does this sound about right? A thousand apologies for the long post but I've been driving myself crazy with this. Nothing worse than ordering a bunch of stuff and then finding out there's more stuff yet to get!
