4.10 rear, 4.09 front. Mechanically they seemed fine, been sitting for 2 years or so. History I know about them is a friend bought a mid 80s K10 with them in it. He bought it for the 35" boggers and 700R4, parted out the rest. I ended up with the axles, engine and t-case.
On the front: One rotor should be replaced. Calipers likely need a kit from sitting. the tie rod is bent, but I have a good one I could trade out.
Rear: was a one ton, Cosmetics, PO moved the pads and didn't clean very well around the cuts, also has some homebrew shock mounts (in the wrong place) that look like crap, I could blow them off with the plasma for him. It's got the big brakes, they worked, but I haven't pulled the drums to check anything.
