Topic: UCX II + QuadMic II rack-mounting side by side

Hi all,

https://www.rme-usa.com/rackmounts.html lists RM19 full-rack ears in 2 versions.
Do the current-gen half-rack units like UCX II and QuadMic II fit into the old Unirack?

As an alternative, I could get a half-rack only and mount units vertically. Where do I get short rack ears for them?
The old-gen stuff, like Multiface II, ADI-2, etc. did come with them.
