Save yourself some the shipping from Great Britain or the mark up from the US vendors and buy these two extra flanges that I no longer need. Neither has been opened and they are just sitting in my garage collecting dust. List price from Bearmach for the pair is ~$50 plus shipping. I'll let them both go for $40 plus shipping. PM if you want more information.
The video below (not mine) shows the repair and part I mentioned above.
