I know this is a bit of an old post, and I'm assuming you got your struts in, but you must be talking about that super PITA rubber damper in the rear end by the transverse spring. Normally, a 3" or so bolt comes with new struts for these models that you put into the damper to clamp it down and hold it there before you remove the strut. If you didn't do that, a clamp of some sort is your only option. Have fun with that one.
