No pictures handy but I had 29x11x15 slicks on my 69 Dart with the springs moved to the frame rails and stock wheel houses. I did have to hammer a couple of spots out on the wheelhouses and roll the lips on the quarters. I had custom made 15" wheels made and it looked like I could have gone a little bit wider, but 12" wide would have been tight.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
