Just another thing that I did on my car when I had it was go to NAPA and buy two terminal strips, Heavy Duty, with 6 terminals on each. One I ran a ground lead to a separate place on the frame and then strapped all the bottom terminals together. The other strip I did with battery and had a cover for it. Then when I needed a ground or battery lead I could just go to these terminal strips and pick up one. I put them on in 1997 and they are still working according to the guy who now has my car. I also had about five other grounds from the frame to the block and other points.
