I did not - mine is currently sitting on a shelf in the rack. I wish I could find some still.
Thank You for your update. ...not sure why there are so many proprietary standards for rack ears. Seems like easier for tier 1 manufacturing if 'they' only have to tool for a smaller set of standards. After all, 'they' did finally settle on the 1U, 2U, etc semi-standards. Someday I will figure out who 'they' really are
...if only I had the time & money, I would start measuring cases and ears for key brands, to build a compatibility data base, or even just a spreadsheet.
