Gauge questions

Posted by Drake On 2008/8/4 15:14:25

two of my gauges have a gold disc in the middle but, the clock seems to be silver. do you think it's just faded, been replaced, or supposed to be that way?

also, they measure 4.25 inches in diameter. replacement gauges are advertised as 5 inch, 3 and 3/8ths or smaller.

i dont want to replace them but, just rewired the whole care for 12v. do i need to do anything to my existing set up to work with all my new volts?
