Dash installation without removing windshield

I take dashes out like this quite often, and zip them back in with sheet metal screws! Pull the cluster, pull the radio and glovebox liner and use a die grinder with a cutoff wheel to cut off the end of the screw! Then just wiggle a flat bar between the dash frame and the flange and pop the frame off of the last thread and it's out! Takes about 1/2 hour to get em out, and about 10 minutes to reinstall them!!
