I need this part 90430-20004, I need it by Wednesday because I will be driving my LS400 Thanksgiving day. Does anyone know which websites ship overnight/1 day shipping? I did a quick google search and found that most places only offer standard shipping. Any ideas?

 

Where are you in Arizona? There are 5 Lexus dealers in the Phx area as well as 1 in Tucson. Not to mention at least a dozen Toyota dealers throughout the state.
Bell Lexus of North Scottsdale has a rather progressive parts department. I'd call them directly and explain your situation...
