Hi Keith,
ALL AM/FM cars could only be had from the factory with a RF fender antenna. A rear antenna was too far from the radio to get a good signal on the FM band for any length of time. It's even more pronounced with a Stereo as the signal is split in half. The dash housing is a flat to eggshell consistency ( the area that the lower aluminum trim moldings bolts too and that the switches mount into). The insert that the cluster bolts into is gloss as is the glovebox door. Don Bock 856-467-7966
