Do I need hood pins if I'm replacing just one hinge?

Hood pins are never required for a hinge replacement — they're a separate choice for hood security. A new hinge will restore proper latching to factory spec on its own.

Will this hinge work with my factory hood latch?

Yes. This hinge is designed to work with the factory latch and striker — no latch modification or replacement needed.

Do I need to replace both hinges at once, or can I do just the driver side?

You can replace just the driver side. That said, if your passenger side hinge is original and showing wear, both will wear at similar rates — test the passenger side first before deciding.
