Yes I had the same problem and if you don't fix this soon you will have stress cracks in the hood where it is flexing back and forth when you open the hood.
I made a skeleton out of 1/2" angle steel for the front to back sides under the hood and attached my hinges to them as seen in the pic., then I took some 3/16 plywood and saw cut out and slowly shaved down some templates for the cross ribs then when I got them to fit under the hood where I wanted them too (the hood must be installed and latched for this part)I took them to a metal fab shop and they sawed them out then I made 4 little feet to go on the bottom of the cross ribs with slotted holes in them for adjustment and welded the feet on to the ribs (which have to be welded on the same angle as the taper in the hood) . Then I had to take the hood back off the car and disassemble it to transfer the slotted hole locations onto the 1/2" angle iron running front to back them drill and tap them , reassemble loose install on the car and latch it down then tighten all the bolts down so the hood now will hold its shape when opened and shut back with out manipulation and bending which is where I got the stress cracks from.
