lol. i totally did the opposite way. i put my 350z's atenna on my girlfriend's is300 because i have a s2000 atenna on mine. She and i think the s2000 and 350z' atennas look much better on our cars so we left the is300 one in the garage.

 

Hey whats up? I'll take that is300 antenna off your hands for you.

 

FYI: the JDM IS300 (Altezza) antenna referred to in this thread is different from the one that comes on the US IS300.
