RE: Question re: mounting an older rack?
It can definitely be fixed. The skull should be fine once cleaned up. Or if you aren't worried about scoring it the antlers can be sawed off and put on an artificial skull. Where in IL are you? I can give you a name of a taxidermist near Jerseyville, If you are close to that area. You could also come up with a cape and do a shoulder mount. They can stain the antlers to look natural. That is what I would do. Those are some awsome antlers.
