Re: 50 gmc gauges
Classic parts sells this gauge for Chevys with V8 engines that has a longer capillary tube on the gauge http://www.classicparts.com/1949-53-.../#.V3M58jXSuX4

Re: 50 gmc gauges
here is the GMC version of mr48s link
http://www.classicparts.com/1947-51-.../#.V3Nrno7F7dQ if you want to know if the gauges have been converted to 12v, check the bulbs, they will be marked 6v if unconverted. most of the gauges are mechanical and 12/6v will not matter (the GMC also uses an ammeter which doesnt matter what voltage), but the gas gauge will have either a converter on it or will have been replaced with a 12v version, which is why I say to check the bulbs. although I did a couple 6v/12v switchovers on VW bugs in my younger days and we just left the bulbs 6v so they would be brighter. left the starter 6v too, extra rpm!

Re: 50 gmc gauges
I've actually been researching the same thing.
Longer oil pressure tube, longer coolant tube, runts resistor, etc... If I'm not mistaken you can buy a converted fuel guage too. VDO makes a 12 heater motor that works also. Don't forget ALL yor light bulbs. Here's a couple articles from Patricks. http://www.patricksantiquecars.com/a...-12-volts.html http://www.patricksantiquecars.com/a...lternator.html |

Re: 50 gmc gauges
Looks like I didn't scroll down the page far enough. I knew there was a difference between the Chev and GMC gauges but couldn't remember what.

Re: 50 gmc gauges
Here's just an idea that I had awhile back. I had some LED tape leftover from a job I did. (I'm an electrician)
I hooked it up to a 14v drill battery. They are bright, but dimmable, plus you can get about any collor you want. BTW, those are cell phone pics, they look alot brighter than they actually were. |
