actually, there's a couple company's that make hydrolic arms. They sell them for the hood, but they're universal, so it shouldn't make much of a difference.
I think Vision and Tein are the two.... check
www.modacar.com or
www.optauto.com
I'm sure one of those two sites sells them
EDIT:
here's a link to the tein hood dampners

it shouldn't be much more different for the trunk....
