I just put one on my 58. It is a heavy vinyl with insulation on the back. It was easy to install as I cut a slit where the harness goes through. It is soft & easy to tuck the new carpeting under the edge. I am very pleased with it except the fasteners didn't fit. I used some large X-mas tree fasteners I had, which fit good but don't have the hole in the center like the original. I got it from LMC.
