<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hazen,     You overlooked the growing action brackets. You should still have time to call Don Mannino with the serial number and he will send out new action brackets which you will then install and bill Young Chang America for your labor to do so. A common problem but if you've never seen it before it's a bit of a head scratcher. Have fun!!!
