Front Disc and Knuckle/Spindle

Hello everyone, its been awhile!

So very recently, my 74 Duster broke a right front wheel bearing!

So, I was wondering, since its drums on the front, I'd like to convert it to front disc.
Now I have heard I can use knuckles from a 75 Volare/valiant.
Any truth to this? And can I use the same ball joints? I was going to replace all 4, so I already bought and paid for them. Even got installed(on the side that broke too!!!)

Any help would be greatly appreciated!!!
