Seems to me the air vent guages are a bad idea ...especially if you are getting boost, oil pressure and air/fuel, thats covering alot of vent space ( especially for us who depend on A/C here in vegas. )
How about the Osir pod shown here?
I would prefer the steering column boost guage and the osir pod for the air/fuel - oil pressure. dont know if thats available though.
too bad about the pillar column not being available due to airbags...does anyone know if they deploy through the middle or if the plastic column flips to the side and the air bag shoots out that way... btw...thats a curtain bag, in front impacts your face generally goes into the steering bag...but if its not known how it reacts i would advise against a pillar guage, would still be interesting to know.
What about a guage on the ceiling column, anyone ever seen anything for a mount up there?
