It wouldn't hurt to take two carpenter squares and set the car up on jack stands with both rear wheels remove and have someone help you use the carpenter squares push up tight the axles and use a tape measure to see how far apart the squares are measured out around 15 inches from the center of the axles under the car to the other square as close to the rocker panels in front of the rear end and then reverse the measuring to the rear and compare the results to see if it is wider (more than 1/8 inch) front or rear And then measure straight up and down to see if it is bent that way or not also
