Many Jetfire owners are not aware that some  ’63 Jetfire  front fenders have different types of spears on the side.  One is male and the other  female.  The first type spear overlaps  the side molding  and the second type spear  is overlapped by  the side molding.  The second type came out later in the year.   Not sure why the difference.  Maybe a change in manufacturer?
