I tried the stealership and they want a lot for the passengers side mirror. 270 for the assembly and just the glass is 140 bucks. To me that is a lot of money. I found some mirrors for older silverados going for under 100. I need to find a place that sells gm parts at a good rate. I do not care if it is oem or aftermarket (aslong as the aftermarket looks stock). The Gm part number they gave me is 512-4828. Also does anyone know where I can find out what other years a compatible with this mirror? I have the heated mirrors and turn signal built in to it.
