Brake lines, which ones???

[sandtoy]

Have an 86 CJ7 and am swapping out the rears. Going with a 1975 Dana 44 in the rear and a 72 thin rotor Dana 30 for the front. new rears are locked and solid axles inthe rear and geared alike

Need new brake hoses so what year do I go with the year of the axle or the year of the Jeep or custom???

any help appreciated

I would find out what size line fitting is on that Dana 44 1st. Being a 75 you have no idea what has been done to it. I know my 72 does not have the stock steel lines. You will most likely need a flare adaptor or two.

What is a 72 thin rotor? Is that a disk brake swap?

I agree with CJ you will just have to check them and see as you go.
Are you sure the spring pads are the same width?
Just wondering why you are changing from WT to NT.?
