3 clusters means 3 shift registers.  You can do it all with one shift register.  Did you know that you can bundle your 3 clusters into one main cluster.  Clusters within a cluster.  Then you would only need one shift register.  See example below:

An alternative to putting your clusters into one main cluster is to wire your clusters into a bundle function.  The output is the same as the main cluster above.
