If you're handy with a rasp and file you can do it yourself. Slim down the whole stock and work the tip into a schnable. Sweeping the pistol grip back further might not be possible but you could get close on your own. There is an article on trimming down Ruger stocks in an old issue of "Rifle" from the 70s. Came out looking nice.
Next best bet is to contact a stock duplicator, like Mike Kokolus,
www.gunstockduplicating.com, or someone else with a duplicator and see if he can inlet a Winchester featherweight turned blank for a Ruger 77II. Have you figured out whether the Win FWT stock will accomodate a 77II dimensionally? Particularly in the tang area, I don't have a 77II on hand to compare but if the tangs are radically different simply duplicating a Win 70 stock won't work.
