If you're trying to install grill badges on an air cooled car you may have some challenges with the hardware originally provided. I've made a 3d printed backing (ABS) with inset nuts.
Here's what my grill looks like right now with a mix of PCA badges. I have a PCA National Badge, 2019 Werks Reunion badge, 2009 Porsche Parade Colorado (which still has the original hardware in place), and a 2026 Diablo Region badge:
I am using M3x0.5x25mm screws. Here's a pic of the hardware I'm using:
Depending on your exact year you may need slightly longer screws. I do not have backers on my badges except for the Diablo one which came with one. In the many years I've had these badges I have not noticed any issue with wear on the black plastic of the grill.
My PCA national badge is the old style one pictured here:
This is what the mounting hardware looks like sitting on my desk:

The parade badge looks like this:

The wing nuts you see are from the Diablo badge and is part of the hardware kit that came with that since it screws in to the back of the badge similar to the newer design of the PCA National Badge.
I was able to install these new backers just holding them under the wing with one hand after it was fully opened manually. I then dropped the screws through the badge and started threading them by hand. I initially tightened up one side. Then I applied blue Loctite on the 2nd screw and installed it. After that was just hand tight (don't over tighten) I then removed the 1st screw to apply Loctite on that. You can opt to apply Loctite directly on the 1st insert but I didn't want to be fishing it around on the 1st screw and the Loctite rubbing off before it got into the inset nut.
STL files are attached. Good luck!
