First, take the mirrors off the truck. Pop off the sail panel and loosen the 3 nuts holding it on, then unplug the wires and release the white clip. The mirror cap is held on with double sided tape and 4 clips where the arrows point to. Gently pry it off and the clips shouldn't break. Taking the mirror out without breaking it is the hardest part. One of mine was hard and the other was easy. This is the back of the mirror. You have to work you way around and pry up all the little clips. A small awl set and good lighting works great for this. This is the mirror without glass. Loosen the 4 Torx (T15) screws shown, and remove the foam pad and white clip. Turn the mirror backwards as far as it will go. You'll be able to get a pick in there to unclip this part. Now the plastic comes off the mirror. Pull the wires out of the hole. This retainer and spring is what is holding the two pieces together. In the picture it is already loose and not compressing the spring. You have to pry the little teeth up until it comes off the shaft. Be careful here because it can shoot off the post and stab you in the face. With the retainer and spring off, you can seperate the two pieces. Now sand all the texture out and get them painted. Re-assemble in the reverse order. One thing to know is it hard as hell to compress the spring and get the retainer back on, but I'm sure it's possible with the right tools. So instead, I cut the spring down a little and it was a piece of cake to put them back together. Also, I bought and extra set of mirrors from a Tahoe/Suburban (without glass) on ebay really cheap (about $50 shipped total). I used the plastic from them to paint so I didn't have to go driving around without mirrors, and those mirrors come with the puddle lamps, which is a cool little mod. Here's how mine came out.
