Looped weld in retainer for the rear seat installation on any 1967-70 Mercury Cougar. This is the front bracket that holds in the rear seat and was used on both coupes and convertibles.
We cut out a section of the floor under the rear seat as shown. Make good measurements prior to removal of your old brackets.
We think that the Ford number is C5AZ-6263370-B, but we have not been able to verify this for certain. For sure that basic Ford part number is 63370.
