I got one of these a while back , detailed nicely . One area gave me fits tho' , the pilot and big air tank . The clearance to the foot boards was way to skimpy . So I played with it for ever until I figured it out !! The pilot screws to the frame , then screws into that big air tank . OK if ANY of these are stripped threads ? You go thru' the frame into a low profile nut to secure the pilot . Then add plastic to the frame to secure the air tank in place . I did that because the frame and the tank were both stripped out ??? Have fun , eh ??? Henry
