Where can I get the version of "The Wild Bunch(1969) that contains all of the graphic violence cut by the MPAA?

The original length of the Starbuck,San Rafael gunfight was 21 minutes long. The climactic Agua Verde fight was at least 20 minutes long! All prints and video versions have had these scenes trimmed down to a mere 5 minutes each! I have heard about the European version being bloodier than the American version! I've spent many years researching,collecting articles, books,doentarie and talking to people who have definitely seen this version! This is my favorite movie! Where can I find it?
