E-brake cables with '89 HD70 diff

[Aruba1]

My truck is a 1972 and I installed a 1989 HD70 differential. The end (pressed sleeves) of the e-brake cables that come out off the hub where cut-off by the previous owners. Also one of the cable housing is messed up. What is the best solution... should I run custom e-brake cables, replace both 1989 e-brake cables coming off the differential or will the stock cables (1972) fit the 89 differential? I can post some pics for clarity :-)
