Hy aggieranch, I know you won't want to hear/see this but I think the truck should have been plumbed with 1/4" line. The flex lines for the front are 17 11/16" o.a.l. and have a 7/16" X 20t.p.i. male thread on one end, and 5/8" X 18 t.p.i. external thread, and 7/16" X 24 t.p.i. internal thread on the other, Raybestos p/n BH4900. The rear hose is 16 7/8" o.a.l. and has a 7/16" X 20 t.p.i. male thread on one end, and a 7/16" X 24 t.p.i. internal thread with an external horseshoe clip slot on the other, Raybestos p/n BH4497, hope that helps.
