Many thanks to the people who suggested solutions to my frozen rotor on my '98 SE. It is original with 66K on it.
Nothing worked however, until I cut the rotor across the face with an abrasive wheel. It took about an hour, but I had wasted 2 days already. It certainly was easier on the front end parts and bearings than getting an even bigger hammer.
