Drum to disc swap

I am swapping from drum brakes to kelsey hayes 4 piston on the front of my 69 dart swinger. I have mounted the calipers on the back of rotor. I am having trouble finding the rubber hoses that will work. I ordered the ones called for (1971 dodge dart donor car)and they are about 6 inches to short. I have ordered several sets (longer) and still to short. Any ideas on hoses that will work? Looks like the hoses needs to be 16-18 inches long since I am using the bracket In behind the rotor. Tia
