I have been lurking waiting to see how this would work out for you and found it very interesting and informative.
I am not presently working on my guages but it is likely i will be soon. I am always glad to see post from folks like yourself who have been their before me to make it easier for us guys that doesn't know where to turn with a repair.
Nice to see your efforts rewarded with a working gauge.
Hope i don't need this repair on my cars, but thanks for sharing even if i don't.

I am impressed and at the very least came away with some good soldering tips for resistors.
