Speedo Recommendation.

I finally got around to calibrating my speedo tonight, and thought I would pass on the experience. Thus far I am extremely pleased with my new guages, but the speedo takes the cake.
In order to calibrate, you only have to drive a pre-measured mile, start the calibration before, and end it after. It will adjust for new gears, different tires and all the other stuff!!! In checking it against the GPS, it's a little off, but you can adjust/fine-tune at will.
Last but certainly not least in reading the documentation, they are rated for EITHER 12 OR 24V. So if anybody is looking for new guages with the old trucks, here you go:
