Hello,
I have a November 65 build date SJ fastback. The right angled part of the fold down back seat does not have a captured nut to attached the bumpers. It has a screw hole like the 65 seats have. The flat part of the fold down seat has the cups for the 66 and not the backstop like the 65. Both pieces appear to be original to the car. Was this a rolling change at San Jose?
Thanks,
Chuck
