I think I have almost broken the code on the anti fiction tape problem. The problem is the previous owner was not the best repairman in the world. There are remnants of glue in places that make me wonder. I have a new strip of factory anti fiction tape plus industrial Velcro. It would be nice for someone to describe in detail two different areas or take a photo of them: 1) On the rear roof panel at the forward most (the top) section of the side extrusion. The outside of it. Whats there? Could there have been an antifriction plate? I am interested in the last 6 to 8" of the outside of the extrusion. 2) on the forward roof panel there is the side extrusion. I am interested in the last foot of the INSIDE of the extrusion. The factory anti friction tape runs along the bottom edge of the forward extrusion for about 5'. It is 1" wide. Is there any other plates of anti friction material above the above mentioned strip? It would seem this is an area that would need weatherstripping. Thanks for the help.
