1990 Honda Accord

You need to perform some measurements to see where and how the car was impacted. For instance, measuring diagonally will probably reveal the 1" difference you are talking about. It is likely that the front clip on the vehicle was pushed back. The front crossmember on the engine that you always lean on with the hood open will likely be pushed back and that needs to be corrected. Sometimes a comealong and tree can help pull in out and sometimes just a big bar can get things straightened out. Regardless, the exterior sheeting will not fit right unless the skeleton on the vehicle is back to normal.
