Hello everyone. I have been toying with what battery to put in the hot rod. I found that Optima yellow top fits and a test fitted it with the back panel in the car. I felt it was to close to the panel that is under the gas tank and in a accident it could ground out on the panel. I came up with a solution that someone else may want to use. I used a rubber mat from a horse stall and I used a router to carve out a groove then I installed it between the top of the battery and the panel under the gas tank. I hope this helps someone. Keep on trucking! image.jpegimage.jpegimage.jpeg
