Im confused on why we are removing 65 and 68 and adding 704, 706, 858. If you could add some information about this to your ticket that'd be really helpful! I took a look at the link you provided here and it looks to me like we should be adding 704, 705 , 706 and 707 so im very confused. Thanks!

Talked to @jacobworrell in parking lot

• letter id 704 correlates to 65 and we were just referencing the wrong id#. It is for Standard 5103 Notice
• letter id 706 correlates to 68 and we were just referencing the wrong id#. It is for 5103/ DTA letter
• letter id 858 needed to be added and is for Custom 5103 Notice
