you will need the SS cluster from a 07 Supercharged to be safe. I know 05 and 06 are interchangeable. 8-10 are interchangeable. going by the blackcat custom gage face page, they ask you to select which option when ordering a replacement gage face. they ask if its supercharged or turbocharged. while both clusters go to 160mph and look identical, the speed marks (50, 60, 70, 80 etc...) may be laid out closer or farther apart which would mean the needle pots may be calibrated differently. otherwise, i'm not sure why they'd ask you to select which one you are replacing. In the end, you may be able to use a cluster from 07 and up but I'd want to be sure ,my speedo is accurate.
