David, the old post was about using a boating cleat and looked decent. But I went with Aerostitch that had a similar design and 4 of them for about $15 or so. Took maybe 10 minutes to install once I decided where I wanted them. Yes, you have to drill into the saddlebags (in the black portion) so be realdamncertain where you want the holes!
That is what I did. I don't seem to have a picture of my Concours saddlebags with them, but below is a picture of my FJR bags. I liked them so much on the FJR that I put them on the Concours when I got it. BTW, I have them mounted on the inside down lower on the Concours - facing the rear wheel if you will, and I have a set on the front and back of the inside of the saddlebags.
