If you open the bonnet on the car you will see its spot welded all along the top of the wing.
grind the welds of remove wing . line new wing up drill a few holes were bolts would be on a normal wing and rivet in place touch up with aerosol . job done end of the day its only a escort no point in payin top money for a cheap car unless its holds a certain value to you ( or its a cossie )
