I bought a replica wing and have a question... on the underside of the base, there are two threaded holes in the rear. That's all as far as threaded holes on the wing. What about the front of the wing? How is it held down?

There are two holes near the front, more in the center of the wing but they are shallow and not threaded. Can anyone give me a little insight into the install?

Thanks~!

 

random. mine had 4 holes, 2 in front and 2 in back.
