I have found that old hoses will swell or collapse and you really don't notice it because you can't see it happening so I would go with NEW lines of any kind. If you like the SS, do it. They won't swell! Check all of the metal lines too, you don't want to blow one when they are needed. I replaced the complete rear with new lines. The only old lines I have are from the fenderwell to the proportioning valve in front. PIECE OF MIND!
