froggy47,
Your suspicions are correct about missing screws in you radiator area. I went out and checked my LT4, it’s stock and has not been altered.
There should be screws in the all of the vacant holes. The “points” and threads of the screws should be visible in your radiator intake area. The flat heads of the screws would be on the INSIDE of the engine compartment. I noticed that your driver side is missing the “clips” that are supposed to be there. The clips are visible in your passenger side photo.
The “L” shaped tab should be on both sides. It rests flush against a larger black plastic piece that continues upwards. Behind the second black piece is the actual one piece bumper.
I
think the little box with the cross hatch opening is the housing for the outside temperature sensor that comes with the electronic climate control option. I
think the ambient air temperature reading is taken here, then displayed on your climate control head unit. If I’m wrong on the sensor, someone will jump in here and set things straight.
If you know a fellow C4 owner that has their radiator area unaltered, you may want to take some shots of how it should be, run the photos out, and give them to the dealer as a go-by. I wish had a digital camera!
Good Luck
