I've got these few left Steve from when I was replacing bits on mine. The larger ones I used for attaching the bumper to the iron bumper bar through the top under the head lamps and grill and the smaller ones for the wheel arch liner.
I think the larger ones can be used at the lower points to near the wheel but im not 100% certain.
I wasn't totally impressed with the smaller ones but your more than welcome to try these and see what you think ( mine are still in and I haven't thought about getting a replacement yet ).
Both I got from eBay so I would say try these and you can order more if they work.
Ill pm you my mob and you can text me your address.
