Rally wheel hub cap center emblem

[dmjlambert]

Hi, can you folks tell me a little about rally wheel hub caps like this? This is 5 lug. It appears to be a single piece of metal, and the center emblem may be foil sticker with some embossing or otherwise raised pattern. Is that a factory thing? Are there replacement emblems that are worth buying or am I bound to get some cheap Chinese stickers that will just fall off? I am thinking of changing the emblem to Chevrolet. Are there choices?
