Excellect reproduction of the door buffers that replace the door plugs. Originals are super rare and expensive!
Just take out your plugs and insert these.
They are made for early cars but if you only have 1 hole plu per hinge, you can razor one of the plug parts off and they will still fit your late beetle. The mounting points measure 36mm apart center of hole to senter of hole. If yours are different, just cut off one rubber piece on the back and fit them.
