The ones that go in each corner of the grill. Has anyone bought these? Are they still avaliable, all mine are broken and so are the ones I find in the junkyard so my grill flaps around at the 4 corners where the clips go. It is only being held in by the screw in the middle. I was just wondering if anyone had purchased these and if they could maybe provide info like price part number, anthing you can dig up or remember really.
