Thanks Dirk, you got me further along. Still wouldn't move much so I resigned myself to trying to get the speedometer out. Taking turns with my husband, we finally got that nut loose. The tips of our fingers are still numb. Turns out there is a bracket on the other side of the ignition. It wasn't really seated in there at all. With much twisting and prying, we got it centered but a bit angled on the right. It's supposed to be straight, right?
