I've had my bags for well over a year (love them), but wife got me the QD hardware for Christmas. A few weeks later I went to install them and found, as others apparently have, that only half of the mounting hardware, docking posts, bolts, etc. was the correct size. My set included 2 ea. of everything in 5/16", and 2 ea. in 3/8". The weirdest part is that it's listed that way on the parts list in the instructions. Also, only 4 of the necessary 8 screws for mounting plates to bags were included, so I had to order 4 more. It appears someone screwed up when the parts lists were printed, and the warehouse people are packaging the parts accordingly. Unfortunately, it took me two phone calls, two more shipments, and over two weeks for them to get the right parts to me. During the second phone call, I believe it was Robert who spent time with me to determine that he was sending me all the missing parts I would need. Once all the correct parts finally arrived, the installation was easy, the fit was great, and I am very pleased. The loss of one star is due to the badly packaged parts, and the ineffective tech support on the first phone call. Once all that was resolved, I'm very please with the whole setup.
