Hello, did you ever find out more info om the D64 77 only lighted mirror question? Like your car, mine was originally equipped with it but was long gone when I finally bought it back. The 994951 option part number gives me this unit I bought, but it does not lool like the one in the phoyo that the Ben guy posted on your thread. Even that one does not look right - I believe it is missing the lid that closes over the mirroe. I have a unit that I believe is a lot closer to the original unit out of a mid 80's Buick with the plastic 'frame" that the mirroe screws to, but it's too big relative to the Legendary visors I bought. Any help would be appreciated.
