reattatch windows locks

[rossboss]

So I'd like to reattatch the sliding window locks on my suburban. Probably the reason they're hard to find is they all came off over years of use. That tells me there was a problem with them from the beginning. To me it looks like they were just sqeezed on with a thin piece of rubber between the lock and glass. So is there a more permanent solution such as a glue of some kind. Anyone that has had success with reattatching these please chime in.
thanks
