We all know the frame is pretty flimsy, but being hollow throughout, couldn't we do something about that? Like injecting expanding foam with a long hose or something? And since the steel only goes so far into the frame, could we stick a piece of round stock up to the corners and weld them to the mounting flanges? Obviously the windshield should be attached before doing so, I'd hate to stiffen it to the wrong shape.

It's just that I know I'm going to be yelling at people trying to use the windshield as a grab handle to get in and out, and I'd like to avoid a broken frame or windshield. Thoughts?
