When I bought my 69 Z the seller gave me a box with one of each of these factory shocks that appear to be brand new. I was wondering what is the application? The correct shock for my car is a 3192851 so I don't know what these are for. Any help would be much appreciated.

You'd probably get a better response in the restoration section of this forum.

Most of the people who frequent the brakes/suspension section here are looking for performance gains rather than originality.
