Replaced the rear shock mounts on the 20013 Bonneville SSEi

A few notes,

Car does not need to be jacked up- only thing that needs be done outside the trunk is essentially taking the air line off the shock so the shock can be pushed down. Very easy to do, I did this with no tools, but did spray silicone lube on the air to shock connection when I put the line back on

Need a 17 and 13 mm deep socket, that is it. Pull out the old and put in the new, no surprises whatsoever.

Do one side at a time, if you forgot how something goes, simply look at the other side (driver or passenger).

I used MOOG as a replacement, super easy fit. Moog (as seen in picture) has modified the original GM design by making the entire shaft opening smaller- GM had a larger shaft opening with three dimples to make it smaller.
