I found some cheap clear corners on my local classifieds and the seller says it fits on 03 04 and 05 but didn't mention the 06 or 07 but there isn't a change in the front bumper or the side marker from 05 to 06 right? So it should fit perfectly?

 

Yes, 03-07 G35 coupe share the same side markers, and 03-06 G35 sedan are the same part. Coupe and sedan side markers are different, though.
