While driving in NZ in My Sister In Law's Miata I also pondered whether it could be adapted to a Trad. The offcenter clamps really put a force on the windscreen to pull the hood tight. But, I wonder, when clamped does the hood mechanism help support the windscreen. I was thinking of buying a junked Miata hood with mechanism and seeing if I could adapt it to MY +8 Bitsa. Another Winter project. Nothing ventured nothing gained.
