I'm looking for plug in led replacements for the original gauges in the car.
Anyone here have a part number and source for them?

Doug,
I've tried half-a-dozen different LED bulbs in stock gauges and, unfortunately, the best ones I've tried (Autolumination.com – item #: 194 168 W5W 2825 SMT Tower – green) are NLA.
SuperbrightLEDs.com makes one that works very well (WLED-GHP5); however, they have an "old" version and a "new" version of this bulb. The "old" version needed some minor filing in order to fit into the bulb tubes on the back of our gauges. They are noticeably brighter than 5W incandescent bulbs. Green, 360 degree LED bulbs give our gauges a slightly greener, "crisper" look than incandescent bulbs. White LEDs make the gauges look very "washed out" and very pale green. The "new" version of this bulb (photo below) looks smaller than the "old" one, so it will probably fit without modification, but I haven't tried it.
So far, SuperbrightLEDs doesn't have any dimensional specs available for the "new" bulb, so the only way to find out if it works is to try it. Just make sure you get the "new" version. SuperbrightLEDs will take them back if they don't fit.
The key features to look for in an LED bulb for OE Pantera gauges are: 360 degree light output and green illumination. Also, the bulb needs to protrude far enough into the gauge that the radial mounted LEDs, on a 360 degree beam pattern bulb, are inside the gauge and not in the bulb tube. Most of the LED bulb companies have bulbs like this but most are too large in diameter to fit into the bulb holder tubes on the back of OE Pantera gauges.
If you use an LED bulb with a narrower beam pattern than 360 degrees, the illumination will be uneven over the face of the gauge.
I hope this helps!

Here are some pictures that may interest you. I found some LED replacement bulbs on ebay from a supplier named allpartspipe. I want to reduce the heat of the bulb inside the gauge. With the incandescent, they get so warm that it causes condensation inside the glass, and my gauges would fog up (the small ones, not the tach and speedo).
Just to see the difference, I set up my gauges on the bench and used a bench power supply set at 13.2 volts. These photos are time exposures taken with the same camera, settings, and conditions. First the incandescents:
Then green LEDs in the next picture:
You can see that the incandescent bulbs are brighter than these LEDs, which are inexpensive ones. I am sure there are better ones available, so I am interested to see what others find.
What I notice is the difference between the gauges. The volt meter is the brightest, followed by water temp, oil pressure, fuel level, and amp meter is the most dim. My clock was out so not visible, but I see in David's pic that it is pretty bright.
My question is how to make them more even in brightness. If I have plenty of light, I can simply add a resistor to the brightest ones. But if the light is weak at best, I need to take the gauges apart and improve the light delivery inside.

Steve,
After installing LED bulbs in all of my gauges and improving the gauge illumination so dramatically, I found I really needed a functional dimmer (since the OEM dimmer won't work with LED bulbs). After trying a bunch of different dimmers, I found one that worked perfectly. I wrote an article for the March '14 POCA newsletter, describing the installation. Here it is:
