Installing SS springs

You will need to get new front mounts with 5/8" hole or drill yours out. Stock springs use an 1/2" bolt. On the back get either rubber of poly bushings for the new rear shackles you will purchase with the springs. I like to put everything new in I can. Your old shackles can be reused if you want. Do not use metal bushings unless your car is competion only. They are to rough on a street car. My findings and opinon's. Jeff
