Chrome trim for SC?
 

I have a 911 SC -80 that would look really good with chrome trim (windshield trim frame, door handles, headlamp sourrounds, fuchs, etc.), but I'm not sure if changing to chrome would be considered as "original" on my car.

Peter Morgan writes that the "black look" became standard in 1980, but was chrome still an option? Other sources yield that chrome ended in 1978.

Was there a chrome package for the SC, and what did that package contain?

Regards,
Daniel
