Spar Guide Dimensions

[Steve Genotte <gopack@sprintmail.com>]

Gents,

I'm about to order some Nylon sheet to make a pair of spar guides.  I'd
appreciate an idea of what their final dimensions are to make sure I
don't order to little.  (I'd know what they should be but I can't refit
the wings for a few days so I'm trying to order ahead.)

Thanks,

Steve G.
