Best way to remove dash?
The easiest way to get the entire dash frame out is if the windshield is removed. There is a row of screws under the bottom edge of the front windshield rubber gasket that holds the dash frame to the car that need to be removed. Then there is a screw on each end of the dash towards the bottom of the dash frame that holds it to the sides of the car underneath the A-pillar.
Once you have all the wiring disconnected, remove the screws along the top of the dash frame, then just loosen the screw on each end and roll the frame back towrds the passenger compartment, remove the side screws on the ends, and the whole frame comes out as one unit.
