• Answer:

  You can get the parts at any auto parts store. A word of advice, I had a 90 Camry and the lines also rusted out, for $50 I took it in to a local shop and walked out a half hour later all fixed up. Those lines rust up pretty badly, so be careful and whatever you do, don't use any heat on the connections.
