Does anybody anywhere know where to find the torsional rigidity of the 914 with the roof off vs. roof on vs. steel roof (916) ?

Thanks in advance.

Chris, are these something you sell or would be willing to sell? I like the idea of additional structural integrity here. Some of us can weld somewhat competently but can't fabricate very well (IMG:style_emoticons/default/dry.gif)
