I'm not sure who actually made the nose and rear bumber. I bought them used from a guy in E.TN several years back, and they are solid fiberglass. I still need to get the side effects to go with it...maybe. It's a work in progress, and by the time I get done, I'll likely not be able to afford the fuel to drive it. ](*,)
BTW, it is a 1980, the mirrors are from a late 80's camaro, I located them and drilled the holes in the doors, then fabricated a spacer that fit the shape of the el camino skin.
