Brake hose

i have a duster from 72 with sway bar and power disk.
now installed the spindels,rotors and calipers from a 75 dart (slider type).
the brake hose (original for 73-76 a- body) is too short!

my dealer says , that the hose from volare/aspen are differend in jear of production. 78 - 80 .
thats my problem.
