Ah crap.. I'm back with my 05 XS
the plastic on the tails take a bit of precise heating for a heat torch.. BUT it's a 50/50 chance you will ruin it because the plastic is quite fragile/thin. I've seen write ups from folks in Japan who've done it successfully, but they don't speak of how. one guy looked like he stuck a sharp blade in there and did it carefully. another looked like he just cut up the black portion around the edges and resealed it with some sort of epoxy. messy, but hidden.
