Given that there have been no replies to your request, I'll take a stab, although I am a novice with Savage rifles.
The Stevens was just recently introduced by Savage. I'm pretty sure that it has only been offered with a synthetic stock. The Savage catalog does not show a wood stock available. I've read several posts that identify the Stevens 200 as the same rifle as a pre-Accu-trigger Savage 110. If that's the case, wood stocks available for the 110 should fit. However, I think there have been a number of design changes with the Mod 110 over the years that may make the stock selection confusing.
That said, check out Numrich Arms. They are a large parts supply house that should have Savage parts/accessories.
Also check out SavageShooters.com. The folks there should be able to help.
Hope this helps.
