How to attach fiberglass hood
'71 Duster, 6 pins on mine. The hood is older one from AAR/Stinger. It's pretty light. The pins are All-Star brand aluminum. Center pins were not installed yet here but you get the idea. The two outer rear pins are in front of the cowl above the fresh air ducts and slightly angled. I copied how the '68 Hemi Darts had them. You have to reach under the cowl to tighten the nuts. I don't have a heater or vent anymore so it's no problem.
Since the hood is lighter, I could see it trying to lift at speed which is why I went with the extra two. For the center pins, I welded on two mounting tabs. One is on the cowl and the other is on the radiator support. I painted my engine bay so this was obviously before the color went on. Edit; I missed that the OP said no welding, sorry.
Painted. hard to make out the rear one but the front one is easy to spot.
Plenty of room for the radiator.
