Parting 1966 barracuda

Interested in the driver's side vent box. Is the lower hinge broken or just rusted? Is it repairable? Interested in the trunk lock mechanism. Not the actual lock but the mechanism that holds the trunk lid down.
Interested in a rear seat hold down bracket. This the bracket that is spot welded to the floor pan and holds down the front of the rear seat.
These?
