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

You can replace just the passenger side if that's the one that's worn or damaged. Many people do one at a time based on what's actually failing. If the driver side is still working smoothly, you don't need to swap it out.

Will this hinge work with my factory hood latch?

Yes — this hinge is engineered to work with your stock latch and hood. No compatibility issues with OEM components or alignment tabs.

Do I need hood pins if I'm replacing the hinge?

Hood pins are a separate safety or styling choice. This hinge replacement alone won't require them — it restores normal hood operation. Add pins if you want that extra security or look.
