12v battery is starting to give out on my 1946 CJ. Currently has a Bosch S5001 on it which fits and gives 52Ah. It looks rubbish, as it is white plastic. Struggling to find a traditional black battery that fits on the batt, tray and gives enough grunt. Do I need to extend the length of the tray or is there another option. I seem to have 232mm of length available between the J hooks and most powerful modern 12V need about 270mm.
How much starting power does the 2.2 Go Devil need? It is the uprated post war L134 with the reinforced head.
