dont know where i read it but i read that you want to keep your battery negative terminal ground short as possible. I saw on a ratrod forum board where a guy made a small 2"x2" square out of 1/8" steel plate. he welded a chunk of 3/4" round bar to that and drilled and tapped the inside for a 3/8" bolt. he welded the plate/post to the frame rail just below the batter box. this is what i plan to do. I think we have an advantage with grounding as our cars are unibody and not framed cars.
