I think mine was an old Mustang unit, I had to widen each axle tube by about 40-50mm or so.
i believe its basicly a bolt in kit, they do the conversion state side to the only model of sierra they got, the xr4ti, basicly a sierra xr4i body with a 4 pot 2.3 turbo engine, they pull the baby 2.3 out and fit proper engines, and uprate the rear to 8.8
