Fronts, I'm not sure about. However, a rear hose for a 1995 Dodge 1500 works great in the rear. I used one for my 2.5" lift and there is plenty there for a 4". If you go to napa's website they list the hose ends and lengths if you want to do some research. If you have a pre 80 cj5, I don't know if any other stock applications would work, it's kinda a funky end on the caliper.
