Hi Todd,
I just finished the installation of John Harmon's turtledeck and rear top skin. He supplies the top skin,(not rolled)and the bulkheads. I ended up cutting off the flanges on his bulkheads and making a flange strip in order to get a good fit. I also used epoxy to glue and fill the voids. John's canopy supplier was a little pricy so I went with Todd's canopies (http://toddscanopies.com)from Florida for half the price. Great looking canopy for $350.00 Plus $160 to Calif. John recomended I use the RV-4 canopy frame and just cut and fit. I did and it's a job but looks good. Now I'm waiting for warmer weather to fit the plexiglas.
You can check the Vince Frazier web site (http://www.usi.edu/science/chemistry/vfrazier/page1.html) to see how the canopy looks. He is a Rocket builder with a great site.
