OK GUYS, I FOUND THEM!! Just got trunk struts for my 2002 LS 430 in the mail from FIGS Engineering in Golden, Colorado. Cost $80 for the set. Put them on in 10 minutes...a child could do it. They work great.

(strangely, I just tried their website and it's offline today! Hope it's just a temporary glitch...will keep checking)
