Hi Bob. I have an '04 Touring Turbo as well. I have done a great deal of research on this and the only balls I found to fit our shifter are at

The Kustom Kruzer kit is great and opens the door to many more balls, but it DOES NOT fit the balls we have with the knob on the top.
Hope that helps, if you find any other options please share.
Mike
