Hello everyone . So I just purchased a very beautiful 2002 GS300 and it is my first Lexus am boy am I impressed. Unfortunately the top rubber/weatherstripping around the moonroof (which totally works) needs replacing. I am great at following instructions and was hoping someone might be able to guide me thru removing the glass from the moonroof as I was told it needed to be removed to replace the rubber weatherstripping. Any of your valuable knowledge would be greatly appreciated. Also I believe I need to drop the headliner as well so any guidance in that department would be appreciated as well.

Also make sure clogged drains are not the cause of the issue before you go thru all this work.
