Hello All,

I'm restoring the Gauge's for my 1953 3100 and I have 3 questions regarding the fuel gauge. 1) Is there a paper insulator on the back of the gauge or does the metal plate go right against the housing? 2)Looking from the back of the housing which terminal is for the sending unit wire? 3)Lastly GMC's were positive ground. Can you use a GMC gauge in a negative ground Chevy?

Thanks to all.
