Pine:
       Back on 1 April 1999 I raised the question: "The manual suggests an outboard rib at the counterweight station (pp 7-33, 7-34), but the SFB elevator includes no such thing.  Is this a remnant of the old stabilizer? "   Marv appended an answer to my post, "That outboard rib you mentioned has been deleted in the MKII tail."
       As for the increase of total rib count from 3 to 6,  are you speaking of the elevator or horizontal stabilizer?  If the latter, I did build a short outboard rib where it appears in the drawing, plus the spanwise segment to close the forward face of the counterweight cutout.
       My manual revision is A2/04-1-99. If  yours is older than this I'd be happy to make a copy of the pages (7-33 and 7-34 in my manual) for you.
