Thanks, again! I'm happy to say it was simpler to fix, i.e., I rolled a wad of gorilla tape and stuck a penny in the middle. It fit fairly well into the place where the 'stopper' had apparently been. The brake pedal now rests against the penny pushing the plunger in, i.e., the brake lights go off when car isn't running, cruise control works and everything is working as well as can be expected from a 96 Outback with 306,000 miles. The next project is changing plugs and that will require removing a few parts, apparently. No worries and thanks again for your help...
