1A Auto and on another thread here, Boost Auto, are great places to check for tow mirrors for our years of trucks. That's where I got mine and have been very happy with them, have had them for about 6 months now and have had zero problems. Ebay tow mirrors are something to stay away from. With the LED turn signal and parking lamp, those will need to be wired for them to work, IIRC. I know that 1A Auto does not sell the GMT800 style tow mirrors with the LED turn signal on them, they sell just the regular plain-Jane GMT800 style ones w/ power upper mirror and manual telescopic mirror.
