Heater cables question

I am looking for a source to purchase, new or good used) the set of 3 heater control cables for my 58 CJ5. These are the chrome knobs (not black plastic) with the chrome screw on securing ring. All 3 mount on a bracket on the bottom of the dash. I believe there are 3 different lengths of cable for each function. I have the knobs, securing rings and the bracket but the cables were rusted in half. Any help would be appreciated!
