I remember seeing someone at Maxus running NOS and had 3 guages on their a-pillar. There was a dual guage pod (i think) and something else holding the 3rd guage up. I didnt take the time to look and see exactly what it was, but I am in need of a 3rd guage. Any options here besides the autometer pillars?

 

I beleive summit sells a dual gauge pod, and a single guage pod. They might have just put both togather.
