These are very high quality reproductions we found in France. They are mounted with genuine BOSCH lenses. According to the parts manual from the period, the factory used all black assemblies with mounts on the back. They're now available in black or chrome, or a combination with black housings and chrome fascia.
These are correct for 1974-1983 911's, Carrera's and 930's. Please note that the mounts are properly positioned in the back of the assembly as opposed to incorrect bottom mounts.
