The shock doesn't go bad but the bushings do. Head for the store and look at the poly bushings. I found a set that fit in there and worked with the sleeve. You should used some glue to hold the two halfs in the tube.
A working dampener does wonders for the feel of the car.
Also, lots of 82-83 A cars (Ciera, Century) with the 3.0L used them. Sometimes you can find some with usable bushings.
One I opened was a spring and not a shock but it wasn't from a Fiero. Some other GM car. Not an A body I don't think.
Rodney should make some replacements with high durameter rubber (poly sucks).
