Yeah, they are the same nasty square plastic grommets that hold the wheel well liners on. The ones that are impossible to remove without breaking. I just had to do that filler neck which rusted out and I could not save a single one. Luckily I bought a dozen on eBay a while back.
EDIT: Here is a listing for 20 of them for half dealer price. I recommend keeping a stock.
