I am getting ready to build form for my turtledeck but am interested is knowing a couple things. First. I am 5' 8" tall. How high is the average turtledeck for someone my heigth? How to test. I have a Todd's Canopy - very flexible and oversized so trimming is no problem. - a liitle rounder than a dragonfly.
Second - Can I move the seat support crossmember cack a couple inches to provide 1) more headroom and 2) a more comfy seat that I can adjust with removable back cushions or adjustable back?
