I know it's a lot of extra work but have you tried to swap the springs from side to side & see if that takes care of it. I know someone back a bit questioned that , but have you tried that yet. It would be a shame to try all the rest & it is something as little as that , you know 2 different springs for the same car. Doesn't seem as it would be , but the cars aren't built by the best people or standreds back then & if it didn't fit right they would do something like that just to keep the line going & let the customer worry about it later at the dealership if it ever came in for a fide or handleing problem under warr. Go ahead & give it a try , of course after you check the a-arms for any damage from when the bushings were put in. Check back in & maybe we can all help you find out what the problem is with our seggustions. If I was closer I'd help you to find it if you wanted the help. I still get a kick out of working on them when there is an ood problem. Rex.
