I have a driver side trunk hinge for a fastback dated 6 11 2D $15 plus shipping. I aslo have the passenger side dated 12 2 D. (This side is missing the factory torsion lever but I have metal to make a replacement), $15 plus shipping. Also factory trunk torsion bar $5 plus shipping
Thought I would mention that though you can use 65 and 66 fastback trunk hinges on either car, if an owner is focusing on originality there are visual differences between the different versions.
Given the Dec date its pretty well defined. If you share a picture of the other side of that passenger hinge then the version could be determined, though from this angle it appears to be from a 66. Also if it's a 65 version the spring arm would be the double thickness version also rather than the single thickness seen on later hinges
Very reasonable prices if the hinges are tight!! IMHO Good luck with the sale
Thanks Jeff, The passenger side is out of my mid march 66 built Fastback. It had the fiberglass trunk lid from JC Whittney on it so the bar was removed back in the day. Both hinges are tight. If I can make a few bucks and help someone else out, to me that is what this hobby is about.
