If you are planning on having a functioning air conditioner(not just connected up for show) you should have new barrier type hoses made up r314a being a thinner gas tends to seep out of the old style hoses even if they are new let alone 40 odd years old. Classic auto air do hoses with one end crimped and the open so you can mark the correct length and have it cut and crimped locally.
