I think you'll find out you did the right thing. Here's my Remington M1903 that bubba had sawn the stock in half on. Looks pretty good for an old girl with a new face lift. Like everyone else, it took about an hour of piddling around to get it to stock up perfect. And she shoots great too.
And I know the sling isn't slung correctly. A friend gave me one of the repop Kerr slings and it's way too short for a M1917 or M1903
