This is a grade 'A' used mirror assembly with no UV damage and has had the mirror lens "re-silvered". Keep in mind a restored lens that is decades old will look good when finished but almost never flawless as the surface of the glass will usually have light scratches and often faint spotting on the backside from previous water damage / staining. Sold outright, no core required. We generally only have black in stock, but occasionally we have colors in stock. In our observations 1967 Mercury Cougar XR7's were all black colored. Ford documentation lists possible part numbers of C7AB-17702 and C7AZ-17700.
This picture below shows the rear view mirror variations from 1967-1973.
