[QUOTE="youdoofus, post: 8572431, member: 664079"] ^^this^^ or this you can use a self tapping sheet metal screw as long as it grips well enough to the metal, but a bolt thru from the bottom wherever you can reach to put a couple wrenches on it and the nut is far better. Even better would be to have a mechanic tack weld said bolt in place from the under side giving you a pretty permanent ground post that will be very reliable. I used a dremel tool to get the paint off the body for the wire terminal, but you can easily get away with using a flat head screwdriver too. If its a sedan/coupe or anything with a internal spare tire cover, you can pull up the cover, scrape some paint, put the terminal against the bare metal and run a self tapping screw (1/2" is all the longer youre going to want) and itll likely be good if youre not pulling big amperages from the positive side of 12 volts. Also will want to make sure that where youre putting the screw doesnt have anything on the other side. If youre worried about rust with the screw going thru, you can hit the under side of the car where the screw came thru with something to coat it (you could use something as common as the stuff you spray on shoes to weather protect them) [/QUOTE]
