What mount did you end up using?
I thought that something like this would have worked well:

CoreMax gives you 60fps pinball play. In your situation, I'd highly recommend it.
For pinball, I really would try to get the screen vertical. There are TV mounts out there that do it.
Looks like the last tenant took half of the tv mount, it will be easier to just get an entire new one instead of trying to find the right replacement parts. Mounts are super cheap.
