Hi chaps, newbie to the sport so go easy on me, I've recently acquired a king blackfoot, I've modified the steering along with a few subtle mods and it's coming along really nicely. What I could do with knowing is can I get a ball differential to fit the kbf? I've spoken to motorsport and they tell me the blackfoot/monster beetle ones are completely different? Am I right in saying the only other truck that has the same gearbox as the one is the bush devil? Many thanks.
