Hy TimBryant, this is a really BIG project to explain! First we need some more information from you, what line size are the ports on your wheel cylinders. There are adapters available for the master cylinder ports that will bring the ports back to a standard tube size, without those you would have to find compatible tube nuts at a wrecking yard. To give you adapter part numbers we will have to know the diameter and thread pitch of your master cylinder ports. No matter what, your brake lines will not be larger than 1/4" in diameter, either 3/16" or 1/4". You will probably need an original tee for the rear axle. My catalog shows the same part number for all three flexible brake lines in a 1958 Chev. half ton, Raybestos p/n BH13841. Those brake hoses have 3/8" X 24 t.p.i. brake line connection ends on them, that is the size for 3/16" brake line, hope this helps some.
