My trucks (2005 model) got the black outside mirrors. I see some previous model trucks around with chrome mirrors on black and some trucks with painted mirroes on black. My question is, Is this an insert that you can install yourself or do you have to buy the whole mirror?

I have seen an aftermaket company that sales the chrome mirror covers. Sorry their name has slipped my mind.

There's also frequent listings for these on ebay, both chrome and paintable. My truck actually has the stock chrome, but I've never looked at how it's attached...

My truck came with the chrome mirror covers and im pretty sure that they are just stuck on with 3m tape just like everything else on my truck. The company that makes the chrome covers is Putco.

If you have the black mirror caps, then yes you can change them. They are held on by douldle sided tape and clips molded onto the caps themselves. Gm sells kits to replace these. These kits includes both caps and instructions for installation.

Mirror Caps: GM part numbers

Silver- 59U - 17800656
White- 50U - 17800657
Sport Red- 63U - 17800658
Victory Red- 74U - 17802411
Chrome - 17800659

Be careful since some of the mirrors are one piece. GM will only seel mirrors as a whole unit.

Look behind the glass and see if there are tabs that look like the end is wider. There should be one by each corner if the caps come off.
