I am looking to get a replacement for the body channels/rails/whatever else I have seen them named. Just so there is no confusion, these are the channels on top of the quarter pannels. I have searched on here, on the web, everywhere I can and I can't find replacements or any for sale. I have even tried to find specs so I can make my own and still nothing. Any help would be greatly appreciated. I just don't know where to find these. Also, has anyone else had this problem of replacing them.....Thanks in advance.
