A lot of NOS stuff is offered on eBay. However, if you buy on eBay, you need to do your own research as to part numbers. Some eBayers have the resources. Many do not. I find the real bargains to be with sellers who don't know what they have and only have a part number or sometimes only a picture.
Just about all the restoration specialty stores sell the same Asian reproductions. For many parts I prefer a good used part. I have found these guys to have a lot of parts and they know what they fit and accurately describe the condition.
