Soooo... For what its worth, I had totally missed this thread before I bought bags from Viking... Obviously if I had seen it, I might not have chanced it, but I didn't, and they had a pretty well discounted 'Cyber Monday' sale the Monday after Thanksgiving... So I went ahead and got some hard bags for my new Wide Glide.
Until I read this thread, I didn't even notice that I was in fact missing something. They didn't send me the mounting hardware that is promised to be included. I didn't notice because I had instead bought Easy Brackets to mount the bags with. Viking makes a knock-off to easy brackets, but the construction isn't as nice, they make a universal bracket so its kind of cheap looking.
The bags I got had the shock cut out, so the easy brackets wouldn't mount up with all 4 holes. I had to drill two new holes in the brackets to be able to attach them to the Viking Bags with all 4 screws. However, I am pleased with the bags so far, and the easy brackets. Both seem to be well constructed. I love having bags now, so I can carry extra gloves, my jacket liner, etc.
Attached is a pic of my bike with the hard Viking bags I installed. They may have forgotten to include the mounting hardware, but I saved $700 over going with the Harley equivalents (which have HORRIBLE reviews on the Harley store - which is what prompted my search for an alternate solution), and they work great with the Easy Brackets.
