Lee, you are very creative and do excellent work. Does Maryland have a vehicle inspection, I know here in PA that obstructing the headlights, the van wouldn't pass our yearly safety inspection. My daughter lives in Waldorf, MD, but I never paid attention to her vehicles for an inspection sticker on the windshield.
We don't have an annual inspection. Only when transferring title. However, if you run historic tags on the vehicle (over 25 years old) there are no inspections or annual emissions testing (I will be running historic tags on my van). However, back in the late 70's into early 80's I built a previous van with a similar grill and it was a daily driver and I never got stopped for the headlight obstruction. Even was stopped twice for speeding during that time but nothing was said of the headlights.
