First picture here is (front) a 2 pin 2841886 (sail panel 68) nameplate, the pins are 5-15/16 apart, you may be able to use these. It was available from Chrysler in 2002, not sure now. If it will work and is NS1, I have a pair if you need. The rear one in the picture is a 3 pin 2786772 (listed to be 68 grille) that is identical other than the pins.
Now, if your holes are too close together for that (say 4-7/8 or so), you will need to use the listed #'s for your application, 3680354-5, which superceded to the 3504807 stick on type in the 84-86 time frame. If you
have to use the holes you will need to find
NOS (or used) part #'s 3680354-5 as it was a specific, oddball size. See next pic for the size difference. from the 2841886 to the 3504807.
