EGT Gauge in a T800

[Biglentil]

Heading into the big city to get an egt guage and probe. Not quite sure where to mount the guage. Every indash guage location is filled in my dash. Was thinking about putting it in the upper console above the windshield next to the speaker. Or is there a better way? Also where should the probe go? Ive welded bungs on in the past but the metal of the doser injector housing looks thick enough to drill and tap direct. I would drill just ahead of the spray of the doser. Is that the way to go or is there a better way? Thanks in advance!
