This is a Guide Glare-Proof rear view mirror that I believe is correct for 1966 Chevrolet Chevy II / Nova / SS etc. and possibly other models...Chevelle Impala?  Anway, it is in good driver or survivor quality.  The mirror glass is not perfect and has some silvering issues.  The mirror head is good and the day / night functions fine.  The stem has moderate pitting but is tight.  The grey rubber cover is good and is still pliable with no cracks.
