Cabrio pre facelift bumper trim removal?

[Semblance]

I'm having trouble removing the rear plastic bumper trim on my pre-facelift cabrio (it has DBs and body color trim). I found two bolts towards the front - one underneath and one in the wheel well, but it seems to be fastened in the middle, and possibly riveted on at the rear, but I can't seem to access the fastening points. I'm just trying to replace the gaskets at the vents which are leaking. Do I need to remove the DB first? Any help would be appreciated!!

Take the two bolts out to remove the metal bumper, then there are several m8 screws that hold on the plastic trim.

Ok, thanks!

for the rear, there are actually 3 bolts. One under the heat shield on the driver's side.
