The OP needs the USDM 11-12 trunk, not JDM inspire trunk lid with reflectors.
You would need the 11-12 trunk lid that has slot for the reflectors, then you also need to drill couple screw holes to affix the reflectors on your 08. The entire conversion will run you slightly over $300 if you get them all brand new.I have polished metal
I don't want the inspire light I want the oem garnish reflector
Link to part numbers.
