Black grade A mirror assembly with re-silvered lens. This is the early rubber version that is big and bulky with a twist knob for the day / night feature. Found on early 1967 cars, later cars used a smaller mirror with either a twist or lever for the 'Day/Night' function.
We also sell re-silvered lenses by themselves on an exchange basis. Sold outright, no core required.
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.
