This 1959-1964 Chevy Impala LEFT/DRIVER'S SIDE Rear Suspension Frame Section is an original GM part that has been cut off a frame. NOTE: The image photographed is for a BOX FRAME. GM had two styles of frames: Boxed (one piece) or Welded (two pieces). There are two ways to determine what type you have: 1) If your frame has a weld going down the length of your frame on the top or bottom OR if you look at the "rear quarter panel" section of the frame on the side of the trunk and it has an open section (shaped like a "C" and not boxed) THEN you have a Welded (2 piece) frame. We carry both styles. Please indicate which style you need as it will make it much easier to weld this to your current frame. IF YOU NEED THE FRAME CUT SLIGHTLY DIFFERENT PLEASE CONTACT US WITH IMAGES SHOWING WHERE THE CUTS SHOULD BE PLACED.
