Anyone have these units on their car? Like or dont like? What gauges should i pop in? I was thinking oil temp and oil pressure? Any other ideas and do i need them? What about the passenger pillar molding....anywhere i can get a new unit? Might as well do both at the same time....i dont want a brand new pillar post on one side then an older 14 yr sold one on the other.....nowhere near new condition. Thxs.
