I had a similar problem on a 93 Regal. I took the plastic housing off where the hood release originally was and was able to get a grip on the release cable. The cable goes out of the cabin near the steering column so you might be able to back track from that point. I would spring for a new cable though as it is a real pain opening the hood with the pliers. I taped the new cable to the old one and snaked thru the engine compartment pretty easily. Good luck.
Use pliers and pull the cable...
it is next to drivers side on floor in front, take pliers and pull up on cable, this will release hood latch
Use a set of pliers to pull the cable even if the plastic latch is broken...
Remove the grill, cut the cable and pull it with a pair of pliers or vice grips. It might even be possible to push the release on the latch manually, after the grill is removed.
The best way to to try to find the cable and cut it and pull with pliers to open if the inside latch is broken. If not then you would have to go in from underneath or through the grill.
That depends on a few things. If the cable has broken at the release handle, you can use Vice Grips or pliers to grab the end of the cable and pull. If the hood is stuck down you can have a helper pull up on the hood while you work the release in the car. If the cable has broken at the latch consult a pro for help. If you get a helper to hold the the hood release open on the inside and tap lightly, with the side of your fist, on the front of your hood just above the grill. This will usually work if the cable is not broken.

Very interesting vehicle, one of my favorites. There is a special tool that slides in behind the door handle to release the "horseshoe" type clip that holds the handle in place. It is like a thin pair of pliers that has a cutout to fit over this clip. After gripping the clip twist the pliers to release and the handle will slid off the splines.

With a very big hammer
I had a similar problem. On mine, the cable broke right inside the car...right at the lever. There was still plenty of cable sticking out so I just grab it with pliers and pull. If yours is broken in any other place, it will need to be replaced.
