These are my new oil pressure & transmission temperature gauges from New Vintage USA. These are their aviation series which i think resemble the OEM gauges pretty closely. Unfortunately they come in red, altho they were more than willing to custom make this set for me in green! I think they came out great, and so far they seem to be of good quality and work well!
I wired them up to be a standalong harness that i can unplug from the chassis harness, this way in the future i can remove the whole A-pillar trim with gauges, w/o having to cut any wires.
