Fitting a boost gauge in driver's side vent.

[InkedMuttley]

What is the next best place to mount the gauge I personally would like to stick it to the side of the binnacle but where would you route the tube through and would you need to start drilling holes I'd like it to look as if had come fitted have got my eye on a leather grain single gauge pod that just sits on the dash and is sticky taped on or bonded...The gauge I'm looking at has a warning light too which is a must as I'm a little paranoid since my turbo blew on my old Mundano
