Sorry, haven't had the time to run this by a dealer but I trust you folks more, anyway. Looking at a used tour pack off a 2004 FLHTC that was not a quick detach mount. Questions: 1)Have the tour packs changed in size any from 2004 to 2008 - in other words will this one fit OK on my 2008 FLHX? 2) Is it pretty straight forward to convert the pack to a quick detach type? I know it's different hardware but are the holes the same or does it require drilling new ones? 3) Will this system use the same mounting points as my quick detach passenger backrest that was put on with the Rider's Essentials package? 4) Obviously I'll have to get the locks redone to use with my current keys. Anyone give me an idea what this costs? Thanks!
