My 9" came from a 1969 bronco. It has not been cut or altered in anyway. It fit right under. You are correct, I use a 6.5" backspace. And yes the wheelwell can be altered without messing with the interior. The inner wheelwell is rounded toward the front of the tire keeping it about 3" from the back of the wheelwell. I simply split the wheelwell in half, removed the inner portion along with about 1.5" of floor over to the frame rail. I bought a piece of sheet metal and made a half circle top and a back for it and welded it in place(kinda like a half a tub). I was sure to keep it back far enough for the fiberglass interior to clear it. I actually have room for a slightly wider tire but i liked the look of the 12 so i went with it and it seems to be working.
