if you are doing a concorse resto,restencil them.if not,just paint the fan.its not anything anyone is ever gonna look for unless the car is being judged at some super show.
I was going to suggest that you could get a rubber stamp made at OfficeMax or OfficeDepot, they'll make just about anything you want. But at 25 bux ^this^ seems like a decent deal. Gotta wonder how many of those they actually sell?
