How to attach fiberglass hood

Four pins on my A12, stock, but a very heavy duty glass hood.
Four pins on my Cortina, on a gutted steel hood with a scoop. Worked fine.
No hood on my Opel, won't clear the valve covers.
Imo, A-body nailed it. A heavy street weight glass hood can use four pins. A race weight hood needs more pins, more dzus fasteners, or whatever it takes to hold it on. A hinged glass hood, can sometimes use stock latching mechanism, sometimes needs two pins, and either lighter springs or a pin thru the hinge to hold it open. (That's what a friend did with his Fairlane, and another friend did with his 351 pinto)
Personally, if I'm getting a glass hood, I wanna save all the weight I can, and I don't want dzus fasteners, so..... as many pins as it takes to hold my lift-off.
