Unfortunately, I ordered the JBR14 and needed the JRB14A.  I didn't realize this, however, until I was most of the way through the installation process.  The gulde bar in the 14 is larger thatn the 14A.  Check you saw to see if there is an A at the end of the model number.  I will give AMAZON 5 Stars for the return process and their outstanding customer service.  One of the reasons I am a repeat customer for so many things, is the consistent, high quality expierence.
