I have a 1974 Camaro Z28. The exterior is medium red, with red interior. The seats, carpet, door panels and sail panels appear to be bright red. The lower dash, console are black. The package tray, headliner and dash pad are a darker red. Is the two different color reds the way it came originally from the factory? I cannot find any photos or doucmentation. Is firethorn red the same as bright red for carpet? Thanks
