cowl grill snaps

Good evening. I just signed uo to the site and found it to br very informative and makes great reading, I would like to start off my firdt post by asking any of you if you could tell me where I might find or buy about a dozzen of the black plastic snaps which hold down the cowl grill under the hood which you have to remove when you replace the cabin filter. They are simple flat plastic snaps, about 10 of them. I guess I will have to travel up North to my Jaguar dealer sometime next week and see if he has them. Love the site. Take care....Gary
