It is a plastic elbow that is known for failing on the Series 2 supercharged engine, which is what you have in the '96 Ultra. Those items can be found in the HELP! section of most auto parts stores. I am unsure of the complete replacement process, but I believe it is somewhat involved, especially if you have not done it before. Using stop leak is one of the worst things you can do, as it gums up everything, and this leak will only get worse. Also, being a supercharged engine, and not the NA Series 2, it does not suffer from the UIM failures that you would have had to deal with in the LeSabre.
Suggestion: Feed it coolant/water until you can fix it, or it completely breaks. It must be repaired quickly (days, not weeks) before you run it out of coolant, and overheat the engine.

You may wish to look in to this thread for reference:

If you have any questions, please post them in the thread you started (this one), and do not dig up the old one that I just referenced. The gearheads should be along shortly to help with any clarifications necessary.

Thank you for the help. I will be stoping at the parts store on the way home. I will also post my findings and what happens when I change it. One more question though. As long as I keep the coolent/ water at a high level everytime I drive and the car doesnt over heat. It should be okay to drive corect?

You could probably get away with it, but if it runs out of coolant, you are out of luck, whether stranded where you are, or overheating. The primary concern I would worry about at this time would be if that elbow catastrophically fails, and dumps coolant. Also the coolant boiling point will be affected as well, as the system is not maintaining proper pressure, so don't go pulling any massive mountain passes or anything either.
