After looking into trying get a flaring tool to reflare the brake line. I could not find one that would handle the heavy wall tubing, about .067". I went with 6mm bubble flared brake line. I took the fitting out of the diff case with me to eye ball the fit up. I also picked up 1/4" brake line fittings and coupler (i have a double flaring tools).{The 6mm and 1/4' brake lines are only a few thousands different in dia.} I cut the remaining nut and sleeve off the old line. I cut the new 6mm brake line in two and removed the bubble inverted nuts. Then installed old sleeve and nut on each half of new line. Bent both lines to follow the shape of the old line and installed to check fit and marked where to cut off the extra line. I then cut off the extra line and installed the 1/4" flare nuts on each half and double flared end. Installed both halves and left loose to get the 1/4" flare coupler started then tighten all fittngs. Bled the brakes and tractor stops with out dropping box blade and FEL to ground. Pictures to follow.
