Here is my setup. using stock G/S saddlebag brackets, and angle iron mounts, with a latch on the rear. The 1600's are a bit big, rear pegs not available for passengers, but the driver can put feet back there.
i sure like your latching system!
I can take more photos if interested parties want more info. My friend told me to get the 1600 case, but didn't realize he had the 1550 on his K100, so the 1550 case is probably better, but for solo riding, these work well. I rode 200 miles in washboard/dirt roads on the way home from Phoenix, and they stayed on through everything.
