358jdj: Check our spponsor list. At least one of them sells gunstocks and may have something for you. If that doesn't work check out the latest Shotgun News - I have seen at least two advertisments for Springfield stocks - military surplus in one of them, possibly sporters in another.
If that doesn't work for you then you can try bedding compound, it works. I had a 8mm Mauser with a cracked stock (cracked in the handle just behind the bolt, but when I bedded the action and applied bedding to the cracked area it sealed and healed it right there. HTH. Mikey.
