mac, wow looks like that conglomeration needed to be smothered in like "Anti-seize" or something.Best that you got "similar"- "pictured" now!
Somebody who's done one before will come on back here and hopefully say SOMETHING.

never seen anything like that myself though to be honest.Just out of curiosity , what did you find this photo online? - why not a shot of your hub - with the one broken screw , as it is on your car to see?
