I have a NG TC and without removing the seats and steering wheel it is nigh on impossible to get access to remove the dash
to remove the dash on my car do as above then get on your back to remove the nuts that hold on the soft dashboard roll on the back of the dash itself
you should find some screws holding the dash itself under the dashboard roll that you have just removed
don't forget to lable all of your cars instrument wires before you remove anything
somebody else might be able to tell you a quicker way but i havn't found one
Good Luck
