For all of those, who have had trouble with the plastic "push in" plastic rivet type fasteners used for the oil change door, I pleasantly discover, by accident, a much stronger fastened of the same type, when I roder the 10mm ones on eBay from Hong Kong. I got these, today, and I am very well pleased. They have much stronger metal inserts. eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices If you look closely at the photo, you will notice the metal insert below the button and out one of the sides in the expanding legs. While this will be an exact fit for the large rivet, they can be used for the holes using the smaller rivet, simply by enlarging those holes with the correct sized drill bit. I also like the idea that, with this modification, all of the plastic push in rivets will be the same size. And, the price is goot at less than $7 delivered. The only downside is that it took 2 weeks to get them.
