ah, maybe you could post a pic, you don't have a hinged model which can swing towards the front seats?
- as I look online I keep seeing reference to your model being a swing-out mount.
I can pics of a piano hinge on the rt side, on the left is a catch and then a ring pull to swing the tv...and behind is pretty much the same amp and electronic I have in my pics
PW on some models has screws up through the bottom of cabinets with small plugs over the screw heads.
there has to be a way in, I am sure.
have you tried the PW yahoo group?
