I'm not sure if you were going to attach photos, but if you did they aren't showing up. On a side note, I'm very happy with my Spiker Engineering mount: Ultragauge Mount ('96-02 4Runner, '96-00 Tacoma) - Spiker EngineeringI figured I would say, here is my location for my ultra gauge. Answer, yes, I did drill into the A-pillar. To mention, the window mount continuously falls off. I got tired of it and did this with my FJ. Anyone wants some details of taking off the A-piilar, I can share. Those videos were hard to come by. Please no hate, not a mechanic, just rigging stuff as a lot of us do
