shocks hitting rear?

Ok, I have some strange shocks and wolfe upper's and lowers. It seems like the pass side has hit the rear, but I don't know how. Everything is tight back there and I had someone come push down on each side of the car. I see no reason that it should even come close. So I put some red spray paint on the rear to see if it happens anymore.

Any idea as to what might be going on or what to look at?

Thanks
