I did manage to find a local dealer that open on Sunday and could place the order with overnight shipping. They could not guarantee it was in stock because their supplier was closed. However, as long as it was in stock it should arrive Tuesday when they are open again.
Just an update from another thread , I did the 19 front and liked it ..wanted to test the 37 rear to even lower the revs at freeway speeds and ordered from PBI sprockets . The 37T aluminum rear part number is as below
