I just had an idea and wanted to run it by you guys. I have a 77 FJ40 and actually prefer to leave the hardtop on year round but would like more ventilation in the summer. I have a tailgate plate that I bolt on when I run the bikini top but just thought about the idea of a canvas cover that would take the place of a hatchback when I have the hardtop on and the tailgate plate installed. With a windshield type channel at the top I could roll up my back window just like a soft top for ventilation and roll it down and strap it or velcro or whatever when I needed less air. Thoughts?
