Yes, the originals were 'glass. Repros are being made also. I forget who had them first as an actual kit, but it seems several of the parts suppliers are carrying the kits now. It's not uncommon to see a truck with Cameo sides put on it, too. I know a local bodyman that has one that he got that way. The one givaway that it was a fake, and almost every fake one has this, is that whoever did the conversion forgot to fill in the holes in the inside bedsides where the original fenders mounted.
Also, on the color thing, '55 was the only year for the single color combo choice. '56 had a few extra color choices in addition to the white/red, though it seems that that was still the popular combo.
