I prefer the European mounts, antlers attached to a bleached out skull. Clean hyde, eyes, and ears off the skull....boil in a large pot of water and (1 cup) bleach for 4-5 hours. Take to car wash and blast remaining residue off. Make your own plaque or purchase one at any outdoor sporting goods store.
For racks without the skull, use a sawzall and cut behind the rack down to the ears and in front of the rack down through the eye sockets. Clean hyde and tissue material off with a knife. Boil remainder of material or burn off with a propane torch and wire brush.
