Not sure on this, but each seem to be made for a single guage only.

What do you have in mind?

If you are converting from 6 to 12 V use a CVR. Use a Ron Francis CVR (constant Voltage reducer) for best results. Read this:

Do a search on Constant Voltage Reducer and tons of info. appears.

Use what Ford used, starting in '57. NAPA # IR1.
