Just a quick update.
Fitted up the new 50mm-2" longer grille today to check the clearance. I went more than I needed to increase the airflow and proportions of the grille. Have 20mm-3/4" of room above the radiator filler cap and the power steering reservoir now.
Got that truck look back again.
The step doesn't look that bad actually, bit like the MB and CJ's had.
I will deal with the guards when I move the fronts in an inch each side. Want to change the shape of the part alongside the grille anyway.
