check the street trucks article from the last issue, they show how to properly narrow an axle housing, and it was for a new f150 too..... if you have the right tools and knowledge, you can do it..... but if you just go out and cut and take some magnets to hold the rear end back together, and weld, chances are it will be off, and just a half degree off of straight will give your rear end camber or toe in/out, and wear bearings quickly, among other problems....
