Gauge Pod- Missing link...

[tw0123]

So I picked up a 3 gauge pillar pod, currently with 2 Equus gauges, a volt and oil pressure... What do you suggest for the third spot? Pictures and links would be great to add to the thread.
Now for the stupid part... What size are these gauges?
Thanks for all input!

pretty sure they are 2&1/16. i think the only place that makes the direct fit gauge pod for our car is pfyc.com. which is what i have and that one is just a different color then mine. but im 99% sure they are that size.

as for the 3rd.. well in my car i have oil press, volts, and vac.
