Just clean up the seams a bit. There's a good chance the butt stock will bolt on with little or no messing about. The forestock can be a little trickier and may need a bit of tweeking with small files, a dremel (soyez prudent!), and /or a sharp pocket knife. I put one of ATI's camo stocks on an Enfield a while back, and have since given it away to a family member. As I recall, it wasn't a lot of trouble... of course, I didn't do any bedding, nor did I sight it in with the scope I stuck on it, so there could be considerable work to do yet.
