you'll need the JDM radiator support or just the T-bar. simply drill out all the welds then your stock radiator support should just pop off... once thats done, take the JDM radiator support or T-bar and line it up but with those weld holes now drilled out, using bolts, mock up the JDM support/T-bar to the vehicle and mount everything together (headlights, hood, grill, bumper, fenders) once its perfectly lined up, take out each individual bolt and weld into place. piece of cake.
