as far as i can make out,the problem is that the late metal wheels are sealed with the axles in them and they are not long enough to go through to the lower hull of the h/l ,so i suppose that brings us to two questions,can the wheels be parted easily to put longer axles in?.or is there a way to extend what is allready their,anyone know the answers,thanks for all the input chaps
