Keep it! Rarities make the car even better! I've never seen an emblem on a 210. One of the kids on here bought a 210 wagon with a cow emblem on the hood. Looked great!
I should have a rear side marker. I'll take a look. I've been coming across a lot of clocks lately (they come with the tachs which I've been selling). If I find another I'll hit you up. Just know that the mechanism in them will be broke so the clock will not work. None of them ever do. If you're handy with those things just replace the mechanism. I put a clock I found in my 210. You aren't just limited to a 2-door hinge. The front door hinges off a 4-door will also work.
