Just a qwick note. My 15' z8 ex with about 600 miles on it had a front shock come apart this weekend on the trail. The shaft unscrewed from the shock rod end. Managed to find the retainer and shaft pin (bent and broke) winched it up a tree and got the shock back together to drive it back to the trailer.
Havnt called the dealer yet but I'm sure it won't be an issue at all .
Just a qwick note, 12 mm open end wrench, there's wrench groves on the bottum of the shafts, Check them and make sure there tight.
I'll be thread locking mine.
