SUCCESS! mrvandelay, sorry bud but I think I got your lights! Two weeks ago, I grabbed a copy of this TSB went to my local dealer and talked to the "not to understanding" service adviser asking to get my headlights replaced now before the 36k/3 year warranty runs out. No go, since my lights were not showing signs of oxidation.
I then wanted to go up the ladder to the service mgr. He was out until the following week. I came back a week later and went straight to him. He understood what I was trying to do, but had to clear it with his "District Rep.". (Replace something that everybody knows EVENTUALLY WILL GO WRONG while still under warranty, even though it really has not happened yet) Two days later, I got an e-mail with a green light.
I then called him back and asked him if it is the same cost, could he order the "TE" lights instead of the SR5....again, no problem. They were installed today in less then 1 hour.
This is for Westwind if he is reading this post. 4 or 5 bolts under the bumper, 3 bolts on top, another 3 bolts at the front of each of the inner wheel cover and without counting the radiator cover, another 5 or 6 clips on top, and the whole front fascia "pops" off. There are "guide clips" that center and hold the fascia to the front, so there is no adjustment necessary. In other words, pulling the front end off our trucks and putting it back on is pretty much bullet proof. After watching it done, I would not be concerned about having your light's changed out now. It would be difficult for them to screw anything up.......be safe.
Oh, and while the front fascia was off, they took off the "fog light bezels" for me and I ordered the TE versions, which just clip in. Now, just have to black out the chrome bumper trim strip!
