Stupid Question!!

[1971ChevyTruck]

I had a friend of mine set my cab up on my frame with new cab mounts and a 3" body lift. When we went to try and set the stepside on the frame there is no room between the back of the cab and the stepside. I got to looking at the cab and it looks li it is leaning back...I think he messed up the cab mount rubbers when they were put on. I was wondering if anyone had a picture of what the rubbers should look like or the had a copy of the instructions since he threw them away when he was done.
