Just to update... I haven't done much yet. As always, been too busy. The truck is in my garage with driver's side on jack stands and wheels removed. I guess I do have decent access to the old line and there doesn't seem to be any unions between the one behind the front wheel and the one near rear axle. I have pryed the old line from the plastic clips, sprayed fittings wih PB blaster and that's about it. someone said to cut the lines at the nut and then loosen it with six point socket, that it might be easier that way instead of using flare wrench. I really appreciate all the input from you all. I'll update again later.
