Cool stuff. Wish I could find pix of my ammo cans on my R80G/S. I've since sold them and bought Jesse's bags. I like the Jesse bags but, ultimately they're really not any better than the ammo cans. They worked fine and the Jesse's only feel maybe a couple of pounds lighter each. I bolted on a piece of 'L' bracket to hang them from the top of the stock rack and the used some electrical conduit clamps on the bottom w/ rubber washers to keep things dry. Not exactly 'quick release' but then, neither are the early vintage Jesse bags.
