I think you can find what your want at Macon Gun Stocks, Warsaw, MO. Just Google the name. I think they might have them in stock.
I was just looking through their site and they have a large collection of Savage and Stephens stocks. It looks like they will also do custom work (per your suggestion), but I suspect the cost would exceed the value of the gun.
If you are like me, "the price was right" means cheap. I just finished a rehab on a Savage Model 430 and I don't know what to do with it. I don't want/need it and neither do my grandsons, but it was fun to rejuvenate it.
