Hi,
We get occasional questions from members of the public and we try to provide useful answers, but please note we are hobby lock pickers, not a locksmith hotline

. It would make more sense to call a local locksmith shop or office furniture reseller in your area if you want the correct part.
The lock you found looks like the direct replacement. Here's one on ebay which may work as well:

PS. Note to lp101 community: Because of the frequency with which the general public finds this forum and asks lock tech support / ask an expert style question, we are looking into having a thread or sub forum dedicated to answering Questions from the Public. Unfortunately in the internet forum world, it seems people join, ask 1 question, then disappear and are never heard from again. I would rather have an special area for visitors who just have a question, but aren't really here to become members of the community.
