Parking brake cables

Ok so I need parking brake cable setup for my 66 Dart but I have an 8.8 ford rear with disk brakes, ant idea where I can get a kit to fit?

I doubt if you find something that fits right out of the box,
If it was me I would start with a rear brake cable that matches the 8.8 ford rear disks then connect that to the OE 66 Dart brake cable,, that is assuming that the Ford 8.8 rear disks have a cable operated parking brake system,,,
