I'll say it does fit all coupes but double check I'm 99.9% it will 03-07

just disconnect the battery before doing it

and the airbag module has to be replaced or reseted (cheaper been reset but idk if theres anything bad by doing that I've done it )

You dont need a new belt ?

 

Yeah I think all SRS airbags equipment is interchangeable as long as it's from the same chassis (coupe/sedan). Fortunately the system is a standalone setup, if your diagnostic control module (brain box in the console) has been in an accident it must be replaced but there is no dealership programming, just install all the parts with the battery disconnected and once it's 100% hook the battery up and turn the key to ON, it does a self-check every time you turn the car on.

Diagnostic control module, driver airbag, seatbelt switches, seat airbags, etc can be from either chassis. It's possible the side curtains are as well but I've never compared them.

 

If the seatbelt auto retractor pin has been popped you need new seatbelts. You can Google how to put the SRS system in diagnostic mode then it will flash a Morse code on the dash and tell you what systems are inoperable.
