No experience with that bar, but....
Cabrhina 2004 User's Manual can be found here:
http://pr.cabrinhakites.com/manuals/zip/ck04um_english_pdf.z...
It's 60+ pages, with a fairly complete section on the bar with pics.
2003 and 2005 manuals are also available, in case the guesstimate on the vintage is off.
ATB,
Sam
