Do or DONT fiberglass body parts

I believe this is there hood and it's not right for a 66. I base that on they are one of the only people that offer it and the picture of the subframe is identical to what is on my hood.
I put some glass front fenders on my son's Duster. The fit was a little rough but they were better than the factory sheetmetal we had. Only reason to do that on a street car.
