The 19mm master is what you'll need. (From what I've read elsewhere.)
I'll let someone else chime in about the lines, but I'd go get a bender, and some lines and do it myself. Used brake lines scare me!
Custom lines are easy enough to build. If you go to AutoZone, they'll sell you a flange tool under their 'learning' program. You cna take it back after you are done with it and they'll refund all your money, or you can keep it.
Just a thought...
