I don't have the money to buy the springs I want yet so I am useing what I have access too. I have a 88 GXL the that AAS crap, anyway took out its shock & spring combo and put in the reg shock & some cut springs off my parts car on all four corners, so should I swap out and use the springs that came with the car, or use springs from a 87 turbo2, or should I use springs from a series 5 gtu. I amm assuming that they are all the same but the turbo ones might have a higher spring weight. Thanks Matt22
