He took some pics of the knuckle tops individually, and they look fairly thick. I know that I can put the 3/4 ton stuff on my 1/2 ton knuckles, and to do that in reverse is just a bit of machining to make the brake parts clear, so either way I'll get them and if they don't work, I'll stick them back on the evilbay and find another knuckle.
Here are the other pic's he took:

Which ones do they look like to you? For $70 to my door, do they look like a good deal for what I use them for and want to do with them?
