yeah, if your getting issues it can be tough to make things right.
not sure of the frame code thing there, i would have to study the laws to see the way thru, but moving to a more reasonable place is the best way....
i widened my fenders to a point, but the reality is ineffectual to thier ideal.
regardless almost all of my windshield issues came from "street legal" vehicles, and the stats proved it out and they quit bugging me with minimal alterations to my vehicle.
i am jealous of your wheeling location...i have been there wheeling a few times since the 80's along with moab/rubicon/hammers trips and its awesome out there.
