Ok -Im looking to put some gauge's in my truck here soon. I want to get a triple pillar pod. But right now i will only be putting 2 gauge's in the pod. 1 boost and 1 Pyrometer. My question is-- has anyone done this before and if so what could i use to plug the hole with until i buy my other gauge? The other question is-- the pillar pod- do i take the factory trim out? and does it go where the trim had went or does the pod cover the factory trim?
