I dont mind drilling holes if I can hide the heads of the screws or whatever hardware I end up using. I was trying to figure out a way to drill a hole through the roof of the mouth and bolting it to the shed, but I cant figure out a way to drop a long enough bolt through the nasal passage to the roof of the mouth. I can get a very short one in there, but anything longer and I cant get it to turn down through the hole, if I drilled one.
