Thanks guys. It is the flange that is mounted to the Diff. I looked at the flange mounted to the half shaft a little and didn't see anything obvious. The serial number on the car is KF20404 so it has the newer suspension design. The reason why I had questioned this is because here in the U.S. Victoria British is one of the best resources for parts. If you look at this page in the left column: http://www.victoriabritish.com/icatalog/sg/full.aspx?Page=120 You can see that part #1 only shows its good till 1972 year. So what I am getting here from you guys is that this part should work on my car? I just don't want to get the wrong thing and delay the process.
