The driver's side parking brake cable broke off inside the wheel at the shackle. After looking over the passenger side, I decided to replace the passenger side cable as well and purchased a brake shoe kit. I have the wheels completed and the cables are threaded through the proper holes and sitting next to the main shackle where the three cables come together.

Does anyone have a suggestion as to how I can get rear cables attached to this shackle? It is not locked up and I have backed out the tensioning screw and removed the spring but I still need about 1/4 - 1/2 inch of length to get the cables over the hooks... I can't find a DIY on this anywhere.

Thanks in advance for any suggestions.
