Broken latch that won't actuate

I Hope with these two pictures you can tell me where to get another latch near SLC Utah, I watched your YouTube Clip and maybe this is your 10-556 Lavatory Latch. the replacement seems simple enough, we just need to get a latch asap.

Let me know, I'm associated with a company, and we'd like to fix this ASAP since it is the only men's lavatory in the building
