Hi Walt,
I am sorry to hear of your problems. I am interested to hear if the bearing behind the clutch has failed. I have long believed this to be high on the list of possible failures. This is why I have designed my upgrade with a front end support bearing. Look in
www.bleazey.co.uk to see how I did it, it is a long read but will put things in perspective for you. I advise you to look at stage three of my kit and get a local machine shop to carry out the work while you have the engine out. The drawings are on my kit page and any competent machinist can do the work for you. Having done this you can change the Centa coupling inserts in about half an hour instead of engine out each time. Do contact me if you need any help.
Good luck,
Phil
