If you would like lines that are pre-cut and flared to the lengths you will need you can get them from Black Dragon here: http://www.blackdragonauto.com/icatalog/zr/full.aspx?Page=89 They used to sell a complete kit for the Z. You'll have to bend them yourself obviously. We had to do a few when we rebuilt our car a few years ago.
I just replaced all the lines on a 510. Used lines from O'Reilly's and NAPA. For really tight bends Rigid makes a neat small tube bender. The hard one to find is one long enough to go from the back to the front. I had to use a coupler on a 260 I replaced the brake lines on.
