Depends on what year the donor cars are.
62-72 the upper control arms have small ball joints. 73-76 they use the large ball joints, which are the same as the B/E bodies.
The lower control arms are basically the same from 62-76, only the location of the sway bar mounts changed. So as long as they don’t have sway bar tabs (or you don’t try to hook up a sway bar) it doesn’t matter what year the lower control arms are.
There’s also two versions of the disk brake spindles, ‘72 down and 73+. The 73+ version uses the large upper ball joint and those rotors are 5x4.5” for the bolt pattern, the earlier disks are 5x4”.
The B/E bodies used the large ball joint for their whole run, so, you can only use the ‘71 Charger drum spindles and brakes if you have large ball joint UCA’s, or buy a set of tapered ball joint adapters from DoctorDiff. And of course those brakes will have the 5x4.5” bolt pattern, whereas your ‘72 and earlier Dusters will be 5x4”.
You can use any year just to get things rolling as long as you’re not trying to mix and match large and small ball joints and bolt pattern parts.
