Stainless braided trans lines

First off, I hope the braided lines you have are teflon lined or they will undoubtably have leak issues. The standard rubber AN line won't work well for long with transmission fluid. Check the Yellow Pages for any industrial supply house in your area that makes up hydraulic lines and they should be able to cut your existing line to the length you desire, permanently crimp on a new fitting and get you back in business.
