Thanks for the suggestion. I called Detours and they were great. They don't use that hardware any longer, but the nice person who answered the phone said she's check around and see if there were any laying about. She emailed me that they mail them to me.

She also implied that the previous owners of the company had made an odd decision in specing these clips and that they now have a much better system.

This is great for me as the bags are in great shape, it's just the stupid hardware that sucks. Thr customer service was so good I figure when I inevitably break these clips I'll buy another Detours pannier set.

SIDE NOTE: I looked at Ortliebs and couldn't do that roll top thing. It made no sense to me at all. Yes, I know they are the best, and many highly recommend them, but I don't get it at all. I do know that rolling thing didn't work for me. It was just too awkward. I looked at a couple of other non-roll models, but at well over $100 for just one it was a bit rich for me.
