[1960HDGMC]

Here are the 1960 and 1961 Operating Guide pages concerning batteries. The 1960 page is first ,and has the B series battery placed differently than the 1961 page. The 1961 page shows it out on the fender step area, while the 1960 page gas it tucked away inside. The conventional battery box that I am dealing with is the same both years. I find it odd that GMC failed to mention the Battery Type in the Operating Manual. I assume it is described in the OPP, but I have yet to find one to read. Does anyone know when GMC changed to the modern type battery tray? Will the first new type trays bolt right up with little or no modification? Any help greatly appreciated, Greg Mead
