Here we go
This is my favorite:
Glovebox
Besides steering column:
Side of Steering Column (second favorite):
By the Dash
Replacing stock gauge (optimal, but expensive install):
I tried the A-Pillar and it blocks my view too much, Not a fan. I'm between the steering column and the glove box if not the stock gauge pod. I have three to install so I would have to get creative with the third one. They would fit really nicely in the glovebox.
I hope those pictures helped some folks out
By the way thats a 60mm Gauge from Prosport Gauges in case someone is wondering.
