Had this happen to me couple months ago. Disconnected the battery, popped the sensor out of the side mirror, used a few squeezes of dust off. Popped it back in and within a couple of days back to normal. No issues to date.
Just visited Memphis for the whole Elvis experience and I definitely know what you mean ( for other reasons ). Was wondering why I saw tire marks at every intersection then I saw 3 dodge chargers fly by at a nice speed and it all came together.
One thing you will get from both a 2 door and a 4 door. They all look alike front the front and the back you have to make up your mind about the middle. Flip a coin it's still a bronco.
Definitely door bags first. Slip em on like a pillow case and pull up. The only problem I ran into was the bag might get in the way putting back on. Had to pull the bag back a little so the bag didn't get in the way of the hinges.
Just remember that bottom alignment pin on reinstall. I didn't on my first attempt on reinstall and fought with my drivers door for 5 to 10 mins until a little light bulb went off and said hey, why don't we look this up real quick.
Looking at these two I kinda realize that Ford did a phenomenal job with the look on 6th generation. The only thing I notice is they could of pitch the front grill a little forward like the original.
