Removing rear speaker grilles

[7825th]

How do I remove the rear speaker grilles on my '78 coupe.
The carpet on them is partially loose & I don't see or feel any fasteners.

I don't know if a 78 is attached the same way as an 81 but in mine the screws are "buried" in the carpet and you really have to feel around to find them in the pile.


Good luck.
