I'm in the process of modifying a NPD battery top with 3D letters rather than the sticker that came with the top. I specifically need to know the height of the letters and arrows on an original battery. I do realize that POS & NEG are a different size. I have been in touch with Andre from the Netherlands and he has helped me some. A friend of mine is a generation 1 MCA judge and suggested Charles Turner might know the measurement and maybe Bob Gaines has one that could relay a figure also. ANYBODY with accurate figures would be greatly appreciated to continue my project. I have been an observer for years but not much in the conversation mode. Thank you very much for all the valued information with my 10+ year ongoing complete restoration project.
