I purchased a pair of panniers from a bike shop in England about 10 years ago. When I brought them back to the US the clips to attach them to the rack broke. I've never been about to find the model online to try to contact the manufacturer and by this point I think it's a lost cause, but I've held onto the bags because they're good bags, clips notwithstanding.
I'm curious if anyone has suggestions for replacement clips. Basically they are constructed with a knob in the back that sits in a plastic groove, letting it slide back and forth. The little knobs are all intact and in principle I could drill a similar shaped clip to screw it into the knob (which has a nut at the back to accept the screw).
