I bonded my fiberglass aar cuda hood to a steel hood inner structure with 3m adhesive. You can remove a lot of the inner framing also, but it really doesn't weigh much. Will use hood pins but will also have a safety latch just in case I forget the pins.

If you want to use just a hinge... using a 2 part adhesive, you can bond metal to the glass and will be very strong.

You just use the outer section of the frame or as much as you want... will fit like an oem hood.
