Yes I lost mine at speed but managed to reach back and grab it. Replace the clips on the deflector. They are essentially leaf springs in plastic. The spring back of the plastic is required to maintain the "lock" of the clip. I tested this out and found how poor the spring action is in old clips. Replace them both even if they are not broken. Carefully pry off the old and snap on the new.

At the bottom of the frame replace the foam pads with Wurth foam weatherstripping cut to size. Stick the new pads on in the same locations.

When you put put your "new" deflector in you will have a nice tight fit
