I'm in the process of doing the same thing but I don't know what my 'guage' cluster came out of. One thing I am concerned about is whether it may have come out of a 6 volt rig. If so, am I going to fry the ammeter when I hook it up to 12 volts? My truck is a 1962 c-30 so what are the possibilities as far as the 'donor' truck being a 6 volt?

The only thing more amazing than my ability to cram 60 minutes of work into a 9 hour day is my talent for making it look effortless!
