Mine had (on one side of the central seam) a strip of the same jute/horsehair/tar mixture pads GM and others used for sound deadening. It was glued on but the side which was there was barely hanging on so I removed it back around 1977. I figure the other side had fallen out sometime before it got it. The piece that was there was about maybe 20 inches by 3 inches. I just used some common self-adhesive foam rubber and cut pieces (about 3/8 inch thick, 1 inch wide and about 3 inches long) to keep the two pieces apart. I removed them a few months ago getting ready to paint the hood. Probably will replace them with the same stuff...got it at a hardware store in a 1 inch wide roll.
