"I Love a Lexus!" I'm having a hard time finding a part for my 2002 RX300. The part I need is the "Outer Grounding/Retaining Sleeve" for my antenna mast. This sleeve holds the antenna mast and antenna tube in place and allows the special nut (and when they said "special" they weren't kidding).to be screwed into the antenna tube. Any help in locating the part, Ladies & Gents? Also, I got the special nut off, but putting it back on ain't so simple. Is there an actual "special nut wrench/tool" ?
