69 dart front disc....

so i went to my local junk yard and found a couple cars i can use the front disc from..first choice is a 82 new yorker and the second is a 83-84 5th ave....

which one should i get...the guys is giving my spindals calipers hard lines master pro valve and what ever else....help before i get the wrong thing

If those are your choices, it doesn't matter. Same spindles on both, probably the same calipers and everything else as well. I'd check to make sure they were slider calipers and not the pin type, but I believe both of those cars should be the slider type anyway.

Keep in mind with those donors you'll still need large ball joint UCA's (or sleeves from Dr. Diff) and new lower ball joints and bolts (LCA bolts from those cars will be too short).
