Disk brake steering knuckle

It depends on the year and the brakes. 9” drums use smaller lower ball joint bolts than 72 down 10” drum brakes, which use the same bolts as the 72 down KH disk brakes. And 73+ disk brake and 10” drum brakes use a larger bolt than the KH and earlier 10” drums.

From an ease of “getting it rolling” perspective just grabbing the entire K frame with the attached LCA’s and just disconnecting the UCA’s and torsion bars is the easiest. And if you do it that way everything will match so if it is a different year than your Duster you can keep it later and have all the parts that go together as there’s some other parts that don’t mix and match depending on the year. But the K frames and UCA frame mounts are all the same.

i do remember the early stuff using small ball joints (63-66 maybe) but wasn’t quite sure on when things changed. I do remember my dart having big ball joints with the fist brakes but completely forgot about them changing over to sbp so he would have a mismatch on the bolt pattern. But that’s not a huge deal, we just need to get it so the tow truck driver and move it and we can get it in my uncles shop. There is 1 75 dart there with disk brakes so that might work. All of the other cars are missing the knuckles so prob just easier to get the front end stuff from the dart there or doing a wanted ad depending on his prices. I have more important things to replace on the charger so disk brakes on my car is further down the list. But that does give us a great cheat sheet for when we’re looking at other front ends.
