Rear end location wrong? IM STUMPED!!!

Going to ask a dumb question having just read thru the installation instructions on Hotchkis website, but verify the new Hotchkis front spring hanger mounting holes are drilled symmetrically in the center of their bracket where they bolt to the car or if there is a bracket with the 4 bolt patter drilled off center from Hotchkis. It would not take much of an error in these holes to get your tolerance stack to go one way or the other but that bracket is not the same one that located your old springs originally and could be the issue with your new springs locations. Left to right swapping those if they favor one side could solve your problem.
