I had this cluster gauge removed when i upgraded to my EI primary instruments. Unfortunately, the oil pressure does not work properly (it is intermittent), and I had it diagnosed as the amplifier that was used in this model mooney. I was planning an upgrade, so never did the repair. All other gauges are working, however. I have no idea what, if any value this may have to anyone, but thought this would be the best place to try. I'll entertain all offers.
I also removed many other items which I'll be listing elsewhere, but message me if you're interested. They include a UBG-16 (4 cylinder), KLN-90B GPS, KT 76A transponder, and KMA24 audio panel.
