With the lower support structure created, I can now concentrate on building the main top cover for the rear of the interior compartment. I am using some light weight Masonite for the cover itself and bracing it all up with some nice straight 1x2s and small trim. I am also insulating the crap out of this piece because it will be used as a secondary heat shield from the engine. This cover will also house the rear 400 watt 3 way 6×9 speakers. When I come to finish the car I will then cover this panel with carpeting.
