I bought a Suburban that the previous owner had a little too much fun with. The mirror was broken and I needed a replacement. I called the dealership and gave them my vin to get the actual part number. The Left one and Right one are one number off from each other. Make sure you check with the dealer before you buy to get the actual number for the right wire harness... They wanted $450 for the replacement. I went with this one and it works fine. It doesn't have the feel of the factory one, but all of the mechanics work perfect. I recommend buying a pair. They won't match your stock one on the other side if you buy only one. But they look good together. -J
