Porsche 155mm Front bumper support tube set for 1959 356A models. This hard to find piece is finally available and made from the original U.S. style bumper support tubes. These tubes have an O.E. 'Adjusting Eye Hole'. A key detail to fit your exact bumper due to all cars being built by hand which can result in a difference in shape. The adjusting eye hole gets you to have your bumper correctly lined up with an area to adjust it correctly.
