I'm at work and can't find it. It might have been someone selling US body parts. I just know I ran across 2 places selling them. It was just a quick search.
Please do a good search for reviews of any fiberglass body part supplier. Some have horrible reps for quality and very slow to no production of the parts.
bumpers can be from a 72-74 duster. that's what my '76 drag car has. i have a glass hood and it's not that lite. have you thought about stripping your steel hood? the inner part does come out, then you just have the skin left.
