Door hinge grommets? ‘65 barracuda

Grumpy Pete,

I am trying to picture what you are looking for- clear as mud for me.

If it is the white foam thin material behind the door hinge to the car’s post... I used a foam pad and trimmed it down typically sold by Home Depot or hardware stores to tighten up electrical boxes between the covers and the outdoor box. A edge ground on a 1/4” piece of tubing and a hammer will cut the gasket on a piece of wood easily.

If I am off track I appoligiese. Alaskan_TA May have put me on the wrong frame of mind with his reply. He is a Super source of reference.
Put up a picture of you can of where you are looking about.
Good luck-
Joe
