This is mine on a Chevy 44HD (1/2" wall tubes), already SOA, so no grinding required. Mine is cut to 56", with no outboarding of the springs. High steer is the only way to go, I couldn't get anything else to work without clearance issues. It's got Jeep outer knuckles, 74-75 Wagoneer spindles with Ford rotors (5 on 5.5" lug pattern). It still runs Chevy backing plates and calipers. The short side axle shaft is factory Wagoneer, the long side is custom cut. The high steer arms are from Tri-County Gear.
