3an male to 3/8'-24 female inverted flare Tee for the axle side. I'm still using the factory lines to the calipers.
The factory brake line has a plastic coating. Instead of compromising the coating to cut and and add a new flare, I bent the brake line into loops about the size of a Coke can to achieve the desired length. (similar set ups as seen from others here on the forums)
