Having gone through a complete ss replumb a few years ago on my camaro I acquired some neat tools. My favorite is the Mastercool hydraulic flare tool. It is pricey at around $300. For ss there really is no other DIY option. [ http://www.mastercool.com/pages/flaring_tools.html ] I have loaned the tool out in the past through other sites. Shoot me an email if interested. I have eastwood hand benders as well.
