I'm using the stock 78/79 620 ball joints. The Hardbody ones have a different mounting pattern and wont work in the 620 control arms.

Yep, hardbody rotors and calipers. You'll nee to get some of the brake bracketry from pull a part. The 2WD v6 trucks had 4 piston calipers spo they are the ones to look out for, but the single piston calipers are still better than the drums.
