Assuming you are looking for the 20 inch radiator core shroud, the C9 versions are somewhat common but differ from the original C7 block-letter FoMoCo version.
Are you concerned which one you want?
The C7 version is all but impossible to find, they are very brittle and usually broken or damaged (often beyond noticeable repair) even if you do locate one. Because of the brittle nature of the C7 version, I would NOT recommend having one shipped since they are so fragile and rare. The C9 version is plastic and safe to ship.
Though I ceased my search because I couldn't find a C7 version, if I ever did and wished to buy one, I would probably end up planning a road trip to ensure it's safe travel.
Good luck!
