first, are 95 mustang bodies galvanized? if they are can i connect my ground for an amplifier directly to the body? all these car audio sites say you need to find a specific grounding place if your body is galvanized. thanks.
I always used a soft stone wheel on the Dremel to grind the metal down to where it was shiny and smooth then bolted the ring terminal down. You can do it anywhere. ANd if you have any doubts, use a continuity tester.
