Greetings . . .
'62 Chevy? What's to convert? Unless I am mistaken Chevy has been a negative ground system since '38. Delco started to take GM to 12 volts with Cad, Olds, and Buick in '53. Chevy and Pontiac followed the move to 12 volts in '55 . . .
I'm with John, can you clarify the application and what's being converted?
