Gizmo Hi!..
Originally, wood screws did all of the hinge retaining/locating on my car, '69 4/4.
After experiencing the futility of having to re-tighten them at intervals,
I did what most others have done. Removed the wood screws, drilled a through-hole and used appropriately-sized
flat-head machine screws - nuts - washers/backing plates. Seems as though your car might have already had some of the
hinge-fixing hardware replaced.
