I recently picked up a wood stock from Numrich that fit one of the newer models. The only changes I had to make was a slight relieving around the back of the action so the old style bolt release would clear. The trigger guard required a shim to make it fit flush in the stock and what I did for that was epoxy a small sink washer to the trigger guard to push it out flush with the bottom of the stock. Works like a charm all the original action screws fit and worked flawlessly. Whole thing took about 15 minutes.
