They can recondition it for you. If its beyond repair, then they may have a replacement, if not, off to nissan you go.
Good luck and let us know how you go.
p.s. if you have an aftermarket wing on the boot which is heavier, this will also be a problem.
On my 33 after puttign the GTR wing on, the struts are not quite strong enough to hold the boot up in a decent wind.
