PS, make sure that you know what rear shocks you need. As I recall, the '88 CRX's had a stamped steel rear lower arm and a eye on the bottom of the arm. The 89 - 91 had a cast iron lower rear A arms. Which arms do you have?

People often swapped arms to work with the shocks they could get. Your car has been around the block enough that it may not have the right original arms, check carefully b4 ordering.
