I think that except for maybe the newest savages that have the release in the trigger guard, any savage will fit into the boyds stock you just have to get the stock for your specific gun. Primarily there are the two different screw spacings on the short actions. The newer center feeds (magazine will stay in the stock when you unscrew everything) have a 4.4 and the older staggered feed (magazine is attached to the receiver) has a 4.2
Also you may want to look into Richards Microfit Gunstocks. Bunch of laminate (or walnut) stocks with lots of custom options. Might end up paying a little more than the boyds (really not much more) but you might find a shape or some options you like better to make it worth it.
