here's a picture of the part from suncoasts website ~ $24 each

on the 986 it's extremely easy to replace......
- remove the two 10mm nuts holding the forward piece of the rear wheel well liner
- remove the three philips head screws on the bottom of the flap (2 will be in the rocker panel area - one interconnects w/ the under body panel)
- remove the one philips head screw from inside the wheel well (hidden by the previously removed wheel well liner)
I would assume the procedure on the 987 is very similar. Hope this helps
