Nakamichi ZX-9 Azimuth Adjustment Wire

I'm in the process of repairing a ZX-9 and have discovered that the blue azimuth adjustment wire is damaged and needs replacement.  It has 237J on a label on the white nylon end that goes to the faceplate (nothing on the black end that is at the head end).  

Any ideas on the part number and where to buy one?

ddzstereo OP: I would just use a very sharp metal drill bit and use cutters not of a scissoring action.  I have no idea about a replacement though.  Most of that stuff is unavailable.  You could contact a place like Mouser Electronics and perhaps they'll guide you in the right direction if they don't have it.  I used them before while searching for obsolete output and power relays as well as obsolete super capacitors and had good luck!  They have a large selection and helpful staff.
