One thing you can see in the Gunsinternational.com ad from Cabela's is that the top tang extends only to the rear edge of the safety and the bottom tang extends just aft of the trigger guard.
There may be a broken stock in your future... or, maybe there is a bolt going all the way through from under the pad.(?)
