Keep your eye out for another classic era used commercial stock. I have actually seen several come up on ebay and go for good prices. Very good in fact. Who wants them? Not long ago a nice one with Schnabel fore end went for a song. I bought this used Mauser aftermarket stock from GunBroker for a couple hundred and cleaned it up for my 404 build. I left the trap gun recoil pad on it (for now). Just fit it properly.

Then you could swap out the safety for a Buhler scope relief safety and change the scope mounts. Those safeties can be had for less than a hundred bucks. Or if the new used stock is cut for it, you might install a trigger block safety. Timney sells them for about $150. It is a shame someone would do so many brutal modifications to a classic hunting rifle just to save a safety that in my opinion was extremely unfriendly for hunting to start with.
