Thanks for the post JBILLUPS ! Sure enough the 2960 stencil shows a new date stamp.  The newer model stencils were added to the original stencil name.  So the 2960S series can be found in the 2960 stencil palate.  The 3560X fwas updated in Oct 2010...

Perhaps we need to know the secret word, or maybe they're geocached somewhere??? I'm installing these models also and stencils would be a huge help.!
