It's Fiberglass but has the weight of the factory steel (if not more). I also searched and never found anyone making Billet Aluminum hinges for A body Mopars, of course, why would they...it's such a small market. I made a program on feature Cam but never actually cut a set out on the CNC machine yet.....If I was building the car over I would go a different route and totally eliminate those ugly factory hinges all together.
