Does the 03-05 Coupe wide rear spoiler fit on the 06 Coupe? I have the 06 currently and am looking to go with the 03-05.

Current rear spoiler.

03-05 spoiler I would like.

^ According to this thread, the holes that were already drilled for your 06-07 spoiler won't line up with the holes required for an 03-05 spoiler.

Your best bet is to try and swap trunks with someone who has the 03-05 spoiler.

You could also try finding a front end collision G35 at a junk yard with the 03-05 spoiler already on the trunk.
