I have done some searching but haven't found an answer to this here or elsewhere on the internet... So I guess you guys are holding out on me.

My Free Bike came with a set of well worn Krauser bags that, none-the-less are structurally ok. The problem they have is that the latches don't any more. I drilled out the rivets holding one of the latches to a bag and removed it to see if there was something I could do to repair it. But I haven't actually found a way to take the latch apart, much less understand what needs fixing.
Does anyone have a method for taking them apart?
