Got both mine today. I had the time to do it on the GP since I didn't have to take pictures or document it.Anyway, a few notes on installs on a 2000 GP.
1. If you have the one piece cover, you WILL have to remove it to cut off the rubber and plastic piece at the end. I know I was able to fix the old GM gasket without removing the entire piece or the wipers, but I'm not that good with a box cutter and pliers! This also means taking off the wipers themselves.
2. On my GP, there was also another piece of plastic that appeared to direct air into the blower. I had to remove it as well since it would have pushed the cover up too much.
It's nice and sunny, and the forecast for my area is nice and sunny for the next few days. But from a product standpoint and install standpoint, they are both excellent. Your pictures of the new deflector do not do it justice once you see it in person. I figured it would be a thin piece of plastic, but it's pretty thick and solid. I even banged the finger guide pretty good and thought it would break, but it did not. So far, a VERY happy customer!
