Hi Jon,
I shared your post with Nick Taylor who designed and commissioned the original Tool Tray manufacture.
Nick's Comments:
Thanks for info on tool tray and Mod needed to fit new roadster.
Cooperman (Jon) solution, I like simple cut ends off increase flange and re weld probably cheaper than a re design!
Best Wishes
Frank
Assuming no one gets mardy over copyright, I intend to sketch up the revised dims for a 5link version of the tray that any TM'er can then pass onto a fabricator
