The steering stops on a T-series are on the lower a-arms. The knuckle contacts these stops, even if steering box internal stops allow further travel. So the front axles won't be affected by steering box changes.
Some wheels wider than stock 8-1/2" rub on the upper rear side of the upper a-arm, and on the tie rod in the opposite direction. My 9-1/2" A-molds do.
