My experience a few weeks ago. I figured what the heck, loosened the nut and beat on the shaft with a 1/2" socket wrench while I pulled up with my knees. Took time, but it worked. No hammer, but I had WD-40. At home, I always use a puller. They are real cheap.
Re finding a new steering wheel, a decent period correct one is very expensive (~$150.), that is why I had to get that JY one. There are some nice after-market ones (Barry Grant), but need adapters, which can be confusing.
