Air Vent Deflectors

These things are complete junk. I went out to the Bronco and slid the bottom piece in place. I started trying to clip on the top piece and I could not get it to clip together. I tried for a good bit at this point. I eventually removed from the car. I then tried to get this put together without installing. I know I would have to take back apart to install, but I thought if I could see how they went together. No matter what I tried I could not get them together. The clips do not extend down far enough. They did not look like everything lined up properly.
