5-speed,
Went out to my PT and looked at the struts. Seems to me, with not too much trouble, you should be able to move either end of the strut a couple of inches from the original spot thereby stopping the the hatch from going all the way up far enough to hit your spoiler. I may be wrong about that, but it's worth a try, or as James said, measure what you have and look for shorter ones. <img src=icon_smile_big.gif border=0 align=middle>
