Aside from being a KI cabinet, it's a fairly standard Midway cabinet. It's used for games like the Mortal Kombat series, Area 51, and other Midway games. Even if you can't find a KI locally you can surely find one of those others.
Games like NBA Jam and Blitz also use the same cabinet, but the control panel is oversized to accomodate 4 players so you may not get the measurements you want. And there are 2 basic variations of the cabinet. The KI games use the full-frontal variation with a coin door large enough for a bill acceptor or 4 coin slots whereas the MK series used a tapered front that could only accomodate 2 coin slots.
I actually have a KI2 machine of my own, but the thing is with my brother and he lives like 10 hours from me. (sorry)
If you do get the dimensions, make sure you post them not only on personal site, but here as well. We could use more cabinets specs, and the Midway cabs may be the best ever created. (Don't forget internal dimensions such as monitor mounting brackets, either.)
P.S. This is my first post in like 3 months! I'm BAAACK!!!
