School me on gauges

I have a 54 chevy 3100. The electrical system has been converted to 12Volt. I am wondering If I can use my original 6v gauges. There are two gauges: The speedo & the cluster of oil, temp, fuel, & amps

The speedo I going to assume I need something to step down the voltage going to it, hook up a cable and it should be proper. (Or am I dead wrong?)

The cluster, I would assume I need to reduce the voltage as well.

-how do I accommodate for a SB350 replacing the stock engine?
(that would affect the temp & oil)

-The gas tank will be a different volume, when I install a new on under the bed.


Any light on the topic would be helpful.
I have some experience with other forms of electrical work and can solder well. So If I can I would like to modify my original gauges.

Thanks.

Hi
The only electric going to your speedometer is for the lights, take your 6v bulb to the auto store & find one that's the same except it's 12v (about same candle power, single contact single filament. about same physical size bulb)
Aren't the oil pressure & water gages mechanical? As for the bulbs do as before.
The gas tank. The sending unit in the tank is an adjustable rheostat.

It should be relatively easy to come up with a resistor to run the original electric gauges if you so desire. Maybe even a Ford or Chrysler pre-electronic ignition resistor would get your voltage where it needs to be. JMO ......Allan

I checked out Dakota, I'm just not into digital gauges. I really like the style of the original gauges. The repop's look good but, are a bit on the expensive side.

thanks for the info gents.

i believe rs3rd is correct in that you have mechanical gauges.
IMO you should bypass the amp gauge or convert it to a volt gauge.
if you add to the electrical system, i don't see a need to run all the load thru your dash.
i converted my 58 amp gauge to a volt gauge.

Hi
That looks nice did you happen to check the price. That price part makes them unattractive.
