Yeah thanks for th replies, however, the question wasn't quite answered.

I was looking at mondeo mk3 knuckles and they look like the ST170 knuckles.

Are they the same knuckles because Ford has a history of parts sharing so I thought that the mk3 mondeo knuckles was where they got the front brakes for the ST170 from.

Here are some links to help.
