Just an update, I placed my order for the LCD panel from www.evisiondisplays.com.
I called and talked with a Bill Hutchins, and ordered this:
EVD084S03-DSOT - 8.4" LVDS LCD w/ sunlight-readable brightness enhancements (~325 NITS) and touchscreen: $392 (was $428!).
Inverter CXA-K0612-VSL $25.00
Inverter input cable 51021-05-12D $3.00
USB Touch screen controller N16B-0558-B710 $25.00
T/S cont. USB cable Cable/RTP/USB $20.00
GA Tax: $27.90
The LCD panel itself is a single-tube LCD, so if you want a brighter one, they have a new AU Optronics LCD model G084SN05 with 2 tubes for $433, but it's 30mm too tall for my car.
The LCD panel is also a newer updated version from the original that I had quoted last year (literally last year, in Feb 2003).
The lead time is about 2 weeks, so it should coincide well with getting my motherboard and CPU..
