Get them from Vans
It took me a while to explain what I wanted, but Van's does have what you need. Ask the parts department to send you "Doc CN-301 TYPE X" (replace the X with 1 or 2, depending on your spar). Less than a year ago, this was a manilla 9x12 envelope that had the PDF files (available to download) but more important, it has drawings and pictures that as far as I know, are not out on the web for download. I think you'll be happier with one of their packets, rather than a copy of a copy of a copy....
If I recall correctly, they said this packet normally goes out with the modification materials, but they split it out from the materials so it could be available for inspections purposes. The idea being one can get materials later if you decide to go ahead.
pinged your email, but posted it here also.
