Brake conversion. Lower control arm swap?

Hello,

I’m doing a swap on a 1971 Scamp drum to the 73 disk conversion. Parts I bought are off a 73 Dart. The parts also came with the lower control arms. I’m looking over forums to see if I can use them without causing and other issues and can’t seem to find any info where they have been included with the swap. If used I’m guessing I can add a sway bar. The car does not have one now.
Also going to swap out tie rods since it will be all apart.

Parts on hand:

PST 1.3 bars
Upper/lower
Upper ball joints
Spindles with sliders
Bushing sets
Proportioning Valve
2 sets BBP rims

Needed:

Lower ball joints
Callipers (size?)
Flex lines
Master cylinder (non power)
Pads
Rotors (size?)

Any info would be great to help me along and other parts needed to be collected.
I have an alignment shop able to get it straight for me.
Thanks guys
