The Zims grommets don't require metal insert and are press fit into the airbag holder after you remove the metal inserts. To remove the inserts, I scraped as much of the old rubber out of the inserts and then worked on one corner of the holder at a time. I heated each corner over a gas stove burner until the middle of the airbag holder felt hot. I then quenched corner holding the insert in cold water. This broke glue bond around the inserts and well as cooled off the metal so I could use a single-edged razor blade to lift the lip of the insert a little bit so I could fit a small screwdriver under the lip to pry the insert completely out. The Zims grommets are very difficult to press into the airbag holder even after removing the inserts. To make the job a bit easier, I boiled some water then dropped the grommets into the water (one at a time) for 10-20 seconds after I turned off the flame. This softened the grommets enough for me to press fit them into the airbag holder. So far the new grommets have worked fine - no more random honking on turns or during braking! I can post a picture or two if people think that will help.
