Resurrecting an old post (it is risen

).... I have a broken plastic latch on one side case. Been Googling OEM ST10 panniers parts list with no success. Any suggestions or knowledge from this group to source a latch (or another box if someone has one...right side please)?
PS. Backstory. Rode my bike 400 miles to a wedding a few years ago and the lock failed. I had to have my stuff so popped the lid. Epoxied for a while but eventually failed. Thus need a new larch. Although running without the latch has been pretty problem free. Just not lockable.
Cheers!
