Hey Andrew: I am pretty sure I have a set of these struts, with the insert still in them, but they can be removed if not required,but I won't be able to tell you for sure until next weekend. Why do you need these struts, don't you already have some off the car that you are going to use the inserts on? What type of car are these units to be installed onto? They will only fit a 33 or Sprint 1983-1986 or 1987 for the Sprint.
Regards...Bob
