Got the factory specs on the B, as follows:

+Inboard end of wing---164 mm forward of T/E

+ At end of spoiler--- 152 mm forward of T/E

+ At inbd end of aileron---125 mm forward

+ Stop at a point 250 mm out on the aileron.

Zig - Zag is better than dimpled tape. I would send you this picture, but I
don't know how to do that.
