Those bushings are shot for sure. but then again no stock bushing was made to last twenty years. You can still get it aligned but it would probably be in your best interest to either replace all those bushings or get after market replacements. Its ALOT easier to get after market replacements. if the outside of your tire is wearing more then the inside i would first grab a set of after market rear upper control arms that you can adjust yourself. I mean if your planning on getting coilovers you are going to need to replace all of those parts with after market parts anyway because you cannot adjust the stock arms once you lower your car. the factory bolts arnt made to correct that.

Also dont waste your money cutting or heating the springs. it will end up costing you more in the future. grab some coilovers and replace the multilink parts right and itl look great and ride nice.
