these were the ones i was looking at..
T5 37 73 74 T5 LED Bulbs For Instrument Panel, Gauge Cluster Lights
our bulbs are a '37' size in the cluster like shown in the pics... that fits All of the bulbs in the cluster... background lamps as well as the idiot lights as well.. my only concern with LED's is will the light be spread properly...
the gauges 'sort of' have optics for the backlights but looks like a decent light spread is needed by the bulb rather than a spot like some LED's produce..
I havent bought any yet.. I wanted to repair my panel first to make sure i could resurrect the poor thing from its abuse before I bought any LED's for it..
if I can create a solution for the trans temp, air pressure, and amps im going to go Glass in that bus with a fully computerized panel...
