What's needed for stock steering wheel change?

The adapter is external and makes the column about 4" longer. Rimblow, Tuff and E body wheels are flatter than the 3 spoke wheels.

I see what you're saying, but mine doesn't seem to have that round adapter between the steering wheel and the column like yours does, if you look at the picture I posted above in post #7. Are we talking about the same style "rim-blow" wheel?
