67 Barracuda New Door Panels

Just received my new 67 Barracuda door panels and they look good. Not sure what the orange round rubber pieces are for. They are not on my old panels - maybe vibration isolators? See pic below.

Also, I had a couple of black plastic type push clips mixed in with the wire ones on the old door. The plastic ones did have a white rubber ring around the base as shown in the pic.

There were no instructions so just want to make sure I get them installed correctly. The other pins were just the regular wire type.
