Expert needed for spring position

Have you measured diagonally from RF to LR and from LF to RR to check the differences in diagonal distance? You ought to be able to look/ask around and find the reference points on the frame for this. I'd do that first and lay it all out on paper with your wheelbase measurements to see if the car is fairly square. If so, then I would look at moving something. Are the springs obviously different? One installed backwards??? (Does not seem possible buuuut.....)
