The fiberglass hood was on the 78s only. They are much lighter than the 79 and up hoods, but not as light as these race hoods. I haven’t actually weighed my 78 hood, but I can tell from lifting it open that it’s heavier.
I picked up a 78 Invader parts sled with plans to repair the hood and use it on the Intimidator until I came across the race hoods.
