Infamous reversing dash frame screw

I actually thought about this after restoring my dash and "sealing" it in with the windshield. In the event someone should buy my car,(so I can build the next one) I'm going to weld some 1/4"-20x1" elevator bolts (flat head ,all thread)to the dash where the bolts go through, remove the speed nuts from the flange and slot those holes the to the inner edge, so the dash frame slides in and is removeable if needed , with flange nuts underneath. and the A-pillar hardware staying the same.
