I don't think he wants to REPLACE Van's plans, just see pictures to help visualize and orient. We have a builder at my airfield, working on my same model, about a year or so ahead of me. Anytime I get confused (often) I walk over and have a look. He also tells me all the goofs he made, so I get to make my own.I suggest staying with the Van's drawing details & builders manual. They will give you all required to attach the canopy frame properly.
