Do I need both hinges or just the passenger side?

You only need this one if the passenger side is damaged or sagging. If the driver side is good, one hinge works fine. If both hinges are worn, you'll want to replace the pair for even hood alignment.

Will this work with my factory hood latch?

Yes—this hinge is designed to work with the OEM hood latch system. The geometry and pin alignment match factory specs, so your existing latch will operate normally.

Do I need any special tools to install this?

Basic hand tools are all you need—wrenches or sockets to unbolt the old hinge and bolt on the new one. The work takes place under the hood at the factory mounting points, no drilling or fabrication required.
