I went through this with replacing the horn ring. Got the official part,
put it in, but could not get the steering wheel to seat. Worked and
worked and worked on it. David Beierl spent a lot of time with me trying
to figure it out long distance. Turned out the new ring had a new little
shoulder that the old one didn't. So it prevented the wheel from
seating. The vendor was glad to learn of this. My fix for the problem
was to remove the metal part from the plastic part of the new ring, then
put it into the old ring. Worked perfect. But be aware - as our vans get
older, more and more of this kind of thing is likely to crop up.
