Need different Lower Control Arms for Front Disk Conv?

[Hyper72Valiant]

Working on putting a front disk brake conversion on my '72 Valiant and was wondering if I will need different lower control arms?

Well...kinda found my own answer right after posting this, hehe..."LCA is the same for all A-Bodies, except for sway bar tab. UCA will be changed if using 73-up big bolt pattern spindles, due to larger upper ball joint. Lower ball joint is the same all years for disk and 10" drums. You will need to change lower ball joints only is you are swapping disks onto a car which originally had 9" drums"

I do have 9" drums all around, so, I guess that I will need to get 73-up LCA's.

I think you should reread that.
It says you need different lower "ball joint", you can keep the lower control arm.
