I tried putting 02 shrouds on my 07 but the the mounting holes didn't all line up so to make it work and look right you might need a newer tank and possibly the seat as well.
i just converted my 05 ec300 to the 07 rear tail, cost me around $500.00 , you need a new, seat, subframe, airbox, and fender, you can use your old air boot assembly though.
