Did you ever figure out a dechroming process for the plastics? Having a hell of a time on mineI'm resurrecting this thread because the paint (over the OEM plastic chrome) is peeling bad and I want to strip it completely, dechrome it properly and prep it right before painting it again. I found the Burco replacement glass on Amazon listed as in stock, so I'll order that and just go ahead and shatter the glass that's in there to hopefully access the screws for the motor mechanism. If I have any luck, I'll update. If not, I'll curse a lot and hate my mirrors.
