I installed my upper upr torque box kit. I got all 4 bolts through the piece underneath and drilled the plate that sits in the car. The plate that sits in the car is crooked. The other pics that I have seen show that the plate sits straight. How could this be if all 4 of my bolts are caught and tight? Also the plate does not sit flush on the floor of the car, like I have seen in pics. Any suggestions? Thanks
