The best way to do this is to use a ratchet with a long extension and from underneath the vehicle remove one of the mounting bolts that hold the latch bracket.

To open the hood of a 1992 Chevy Caprice with a broken latch, you can try pulling the cable from the inside of the car if it's accessible. If that doesn't work, you may need to use a flathead screwdriver or a similar tool to pry open the hood at the latch mechanism while someone else pulls the hood release lever inside. Alternatively, you can access the hood latch from underneath the vehicle, using a tool to manually disengage the latch. If these methods fail, consider seeking help from a professional mechanic.
If the inside latch is broken, you can try manually releasing the hood latch from the front. Use a flathead screwdriver or a similar tool to gently pry open the hood release mechanism, which is located near the grille. If that doesn't work, you may need to access the latch directly by removing the front grille or panel to pull the latch wire or lever. If you're uncomfortable with this, consider seeking help from a mechanic.
