RE: How many of you have mounted your deer with a different cape?
I have no idea about the tag, but a call to the DNR should solve that in short order.
My father had a cape swapped out after the old one cracked due to a combination of poor taxidermy work and just plain old age. Looks great and the "new" cape had great character as its one ear was all torn. I don't think that it is ideal, but you have to do what you have to do.
