One thing you guys can look in to.
Buy a spare pillar cover from Nissan and graft on some gauge pods then cover it with synthetic suede or cloth to match the rest of the car. You can the cover the passenger pillar in the same material to match.
All you'd have to do is trim some of the universal pod material for a fit, then JB Weld in place and cover with material. That's how the one in my Challenger is setup and it looks stock.
