FWIW, Autometer showed at SEMA a new display (called the SD7) supposedly coming in March or April.
Numerous screen options, configurable for any gauge combinations you want, warning lights & alarms, etc. Also has CAN connectivity,etc, etc.
Here's a few crappy cell phone pictures I took of the various screen options on their display. Sorry for the blurry shots...
At 4-5/8" x 7-7/8", it is almost identical in size to the Holley display. To fit it to the DSE dash insert, the drop down will have to be removed or at least notched out. I like the idea of recessing it like Paul did on his Camaro.
