I had never seen how the Dearbourne Deuce was braced before Ken posted those pics. I'm surprised because I also used 1 x 3 box tubing for the cowl in my 30 Brookville and I incorporated my Hagan hiden hinges into this 1 x 3 tubing which made my cowl way stiffer and also added support/stiffining to my roadster doors. My column drop feels like it is set in cement and this tubing like others mentioned has helped with attaching everything.
