Clips to hold shroud to radiator

1970 Duster 340.... car didn't come with a radiator shroud, so I just ordered one, but need the clips to attach it to radiator, and also the screws.
Clips look like this, and I need 4.
Or, if you could let me know where I can order them online or buy them locally, that would help a lot. Got the pic from fellow member.
