The battery is just an off the shelf B2618 from Braille. I think I bought it from Summit Racing. The rod shifter is fairly simple. Just a piece of tubing with rod ends on it that was bent into a S shape. It connects the shifter to the linkage on the transmission. The rod takes up a lot less space than a cable but it has to be bent correctly and cut to the correct length. Shouldn't be too difficult for the average chassis guy to make.
