Fair driver quality condition 1980s Mercury Cougar  sail panel emblem/badge set.  Has discoloration, scratches, corrosion. Mounting studs cut, will need repair.  I've had success cutting nails or screws the same length, width as originals and JB Welding them in place on the emblem.  After it cures, you can secure it to the vehicle using spring clips or nuts/washers - as long as you don't over tighten and put too much pressure on the donor studs, they hold well.  I've done this on a number of my classics and it works well.  They don’t need much to hold them in place.
Please see pictures and condition descriptions for better idea on overall item condition and thank you for looking!
