Chris, what a wild afternoon! We have had at least 3 tornado warnings in the last 2 hours, tons of rain and hail. I snapped these pics in between storms. As you can see, the ground is very wet, so I didn't get a great pic of the lower control arm mount/shock mount clearance. I just pointed the camera under the car while trying to keep out of the water. It appears that the shock is actually partially inside the rim, this would only be worsened by a 6.5 b.s. wheel, and would probably necessitate moving the shock, but that would be the least of your worries, as I still think that the frame would need to be moved to clear that much backspace with a stock width rear. I hope these pics help. The rear view is from about 15 ft back.
