Well, I finally had a project that was much easier than I planned on or expected. I should go play the lottery now.
The door panel removal was quite simple. Pop off the black plastic panel on the opposite the mirror. Remove the visible screw next to the interior door handle. Pop off the two coverings on the interior door handle and the power windows/locks. Remove four more screws (shown below).
I replaced the '07 style mirrors with the '06 I purchased from Bronco_Hauler. They work great!
