Need Advice on '65 Barracuda Brakes...

65 didnt come with any prop valve, just a distribution block (4 port manifold) off the single pot MC. 1 in/2 fronts out and a rear out. Brake lines can delaminate and swell inside. Buddy took his bosses Ferrari F40 out for its quarterly spin around the block and he came back dragging the left front wheel all the way down the parking lot. Brake line just swelled shut under pressure! We cut it in half and it was a solid rod of what used to be rubber. "Hey NAPA, you got a front left brake hose for an '87 Ferrari F40? ......no? OK. Try Autozone? sure...thanks..."
