I have a chance to get a complete running square nose and a round nose hull. But I was wondering if everything is transferable to the rn hull. I know the sn gas tank has the filler neck in a different location but if I cut it up and made an internal fill would it work? Same shape? And are the pump and Midshaft and everything the same? I know the handle pole won't work. Just need to know if all the running gear will bolt into the rn hull.
