Need Instructions For Re-Calibrating "Custom Rod Gauges" Instrument Cluster

[lightman45]

I have a "Custom Rod Gauges" instrument cluster in my '55 Chevy, it was in car when I purchased, so I don't have any instructions. I changed ring gear and pinion and now need to re-calibrate speedometer. Can someone please help me with instructions for re-calibrating this speedometer, or even better if someone could send me a copy of the installation manual with these instructions. I e-mailed the company but no answer. I also called the contact number but got recording that it is no longer a working number. Any help would be greatly appreciated. Thanks, Jim

I have heard that the customer support from the company is really bad on these gauges, and that they're not very reliable. I can't help you with the re-calibration process, but I imagine it has something to do with driving a mile and counting the pulses from the speedo sender. Maybe someone here has the instructions.

Found this for ya...I read that the speedo they use is actually a VDO.

Let us know how it goes. :)

Thanks for the help. I contacted VDO and they sent me the same instructions. I haven't tried it yet but I'm sure it will work. Thanks again.

Dang, back before there were more than 3 elements in the periodic table (earth,wind,fire) -- we used to have an adjustable screw on the speedometer's sending unit coming out of the transmission. In retrospect, "how quaint".

I just bought a 55 Chevy and need the instruction for setting the gas gauge for a set of custom rod gauges.
