How hard would it be to fix the latch on these Jesse Panniers.
 

I've been looking at some Jesse Panniers on ebay for my 2006 BMW R1200gs. They are used and apparently need one of the rivets fixed that a latch catches.

How hard do you think it would be to fix this latch? Do you think I could just fix the rivet catch, or would I need to source a whole latch from somewhere and install it?
