This is a good used secondary hood latch hook. This screws into the front of the hood and hook to the radiator support when opening the hood. This was removed from a 1989 Classic Saab 900 convertible, and it also fits the sedan and hatchback models. This is spring loaded so it automatically catches the hood on its way open. Originally had a piece of plastic riveted to the hook where it rubs the support.

This is the one with the plastic piece for the extra $
