I'm trying to find out some part numbers for labels on a 1978 450SL.
The labels are located on the radiator support; there are three of them. Mine are all faded and I can't make out the part numbers on them.

Label one is to left of the hood latch as you face the front of the car. It's just above the VIN stamped on the radiator support. I think it's black. It is about 1-1/4" x 6-1/4".

Label two is directly to the right of the ID tag on the radiator support. It looks like it says Automotive Air Conditioner - that's about all I can make out. It looks like it's red or orange. It is about 1-1/2" x 1-1/4"

Label three is right next to Label 2. It is about 1" x 3/4".

I think there is a part number on each one of these labels. Does anyone know what the part numbers are?
