Very attractive product. I wish it fit the existing hole pattern on the door, but it did not. In fact, your product had a much smaller footprint, such that did not cover the existing attachment holes on my door. I ended up scavenging the parts I needed and rebuilt the original mirror. Works fine, but not as nice. My "fit" rating should be 0, but the website wouldn't allow it.
WCCC Response: Thanks for emailing pictures of your car, it's clear that the mirror you had on your door was from a Mustang, which has a different base, and someone put holes in the wrong place on your door to make it fit. If your Cougar still had its original mirror, this new mirror would be a perfect fit. We've installed them many times. This is unfortunate in your case because there's no easy way to fix your door, other than welding up the incorrect holes.
