Probably not the feedback you're looking for but why just the a-pillar mounting pod? I find those pillar pods to be rather ricey and actually quite an eyesore on an otherwise tidy interior. I had my boost gauge flush mounted into the driver side air vent with a black trim piece surround. The only alteration to the car was a small hole drilled into the vent ducting behind the dash in order to pass the wiring and vacuum line through - otherwise, the vent can be reinstalled as if it was never touched. Although probably not as good in terms of sightline compared to a pillar pod, I find this mounting method to be a good alternative - neat, tidy and bears some resemblance to stock. I ended up going with a 52 mm Autometer guage that I think you mentioned - black face, white lettering, red needle and green illumination (the gauge comes with both orange and green illumination rubber pieces to fit over the bulb). Goes to 20 PSI and measures vacuum too. Got it for $70 Canadian at a Mopac race shop which carry a ton of gauges and practically all the Autometer & VDO gauges (are there Mopacs in TO?). I'm very happy with this setup, the gauge matches the dash perfectly (right down to the red needle and black background) and it looks like it belongs there.
