Hi, I am looking for some information on the HDX572MDPL cables. My upper cable is showing a some rust and I like to replace it next spring. Has anyone on here replaced their cables? My tower was purchased used and the documents that I got with it have no information on size or length of the cables or the best way to change it. I know that I can order them from US Tower as a complete set, or measure the upper cable that I need when I lower the tower again next spring. Just hoping that someone has done it before and can give me some help up front. Juergen N9RD
