I sell all the GM OEM mirrors including the "full-featured" mirrors (power, heated, built in turn signal, puddle light, power fold). I'm listed in the vendor forum also. The full-featured mirrors are $250/pair shipped USPS Priority mail to your door. This would be the easier upgrade path ... once mirrors are installed you will most likely have to take truck to dealer to have them reprogram your computer with the RPO code 'DL3' I believe. Feel free to contact me if you have any questions. tophog(at)comcast.net
