The grab bar hoop started out as strictly entry/exit assist. I've known from the start that I'd not be able to use the body for support, and support is a must for me. It wasn't till later that a duh bubble burst and it dawned on me that it would work for steering column and hinge support.
If I can work out a good way to do it, I want another hoop at the rear...just high enough above the body to make it grabable. The problem is going to be mounting points that will not prevent body removal.
For windshield support I'm sailing into uncharted waters. First off, I'm not using a formal windshield... I'm going with a pair of Brooklands racing windscreens....

They will mount along the top of the cowl/dash, with 2 feet each. I could probably get by with metal plates on the underside for reinforcement...but I'm planning on something else. I'm hesitant to go into detail until I've actually tried it, because I would hate to have someone else try it, and have it dangerously fail at highway speeds. In general terms it involves using a marine product intended for casting boat transoms and such, to fill the underside top of the dash/cowl...then fastening the windscreen feet through the fiberglass and the cast material. If it works, the whole top of the cowl/dash would have to break off for the windscreen fasteners to pull through. Plus, since the casting material is tappable, it would make for solid mounting of tonneau cover fasteners.
I know that most of my plans will change when it actually comes time to do. I just like to have somewhat plausible plans for everything, and having those plans seemingly mesh with each other. I'm hoping that doing so will help prevent making big mistakes when I commission having the frame and bracketry built. I'm only going to be able to afford one shot at the frame, and I'm REALLY paranoid that I'm going to screw it up.
