I have had already my complete LHS side case replaced and it came with the new locks. I could confirm immediatly that they're much better.
Although the irish importer didn't want to pro-actively replace the lock on my 2nd side-case... and denied any service bulletin regarding the locks.

I'll be trying to get just the lock for the RHS, but it took more than 3month to get the 1st one replaced ....

About the rubber, I remember reading in a thread that someone drilled through and used a cable tie to hold them in place.
