Performed initial mounting of firewall to longerons and forward bottom skin. Drilled and clecoed 2 places between bottom skin and firewall angle in order to set firewall distance from F704. Performed initial alignment of firewall by clamping WD602 brackets to longeron webs and measuring 5/8" from front of firewall to forward edge of sideskins. Also, ensured alignment of sideskin rivet holes with longerons. I will let this rest for a day, per the instructions, and will recheck alignment before drilling firewall angle to side skins.
