Do I need different control arms?

Hi all;

Quite a few years back I pulled brand new rotors,spindles,4 piston kelsey hayes calipers,master cylinder, power brake booster,proportioning valve,and brake lines from caliper to master to valve from a wrecked 68 Cuda.The calipers have a small bolt pattern.And yes everything was new...

I still have all this stuff.Havent yet installed it due to life in general,lol,I know lame excuse but the 70 Dart it's going on is a BIG resto project thus collecting parts still.I just grabbed the stuff because of a ridiculously low price!

Anyways,my point and question is this.I did not grab the control arms from the Cuda,nor ball joints for some silly reaon.So in order to install these disc brakes on my Dart which has 10" drums,what do I need?Do I just get the disc ball joints,and maybe some clearance grinding on the lower control arms?I do know that by now the caliper pistons are probably stuck,so I'll have to do something about that.

I know I have asked this on another forum,but it has been years...
