I am a l33t Ebay ninja.
The seller is just on the other side of New Orleans, about 2 hours away from me, so I emailed him to see if I can just pick the monitor up in person sometime in the next couple days. The screen is listed as "new" so apparently he bought the screen for a project vehicle, but never installed it. Looks like I've solved the touchscreen issue, pretty much all I need now is a power supply and a few other misc. items. Also last night I did some work on the truck. Ran all the 1/0 power and ground wiring for the sound system, and included provisions to easily add a battery isolator and second battery to power the sound system, CarPC, and anything else that I might want to add (I have 2 extra 4 gauge power and ground connections on my distro blocks). I'll take some pics later on to post up, but for now it's about 7:40am and I haven't been to bed yet, so I think it's time to get some sleep.
