RE: grouse kit?
Just get what you need to mount the Grouse: a grouse body form, a pair of eyes, some small wire, and some Borax. The Van Dykes website has some walk throughs posted. I'm not sure about Grouse Mounting, but any bird mounting how-to would give you the basics, you just don't have to degrease the Grouse as you would a waterfowl species.
