i think i like the gauge holder in your car, but with the tach next to it, it might be a bit too much to be sticking out under the dash.
i always appreciate gauges well constructed in the dash.
i made the panels myself from plain ones. i cut out the contours of the gauges, stuck some wax to the back and filled the ribs on the front with filler and painted them.
quite some labour, but very rewarding to do it yourself, plus you can think of any design of the gauges. (and it's cheaper, but that's me as a student with not too much budget)
these are my panels:


might be a big rig of gauges but you can design your own setup.
