The plastic screw-rivets are in two sizes. Those attaching the liners to the metal panels are 8mm (that's the hole size). There are four or five of these. There are also two 10mm ones that go into the front subframe lower face. You can get them both on eBay. Ensure to buy the screw-type (with 20mm heads) or they may not expand enough to hold the liner. I know all this 'cos I wasted a fiver on push-rivets that didn't work.
