Thanks for reporting back, Mike. With those final reports I'll close this thread. However, please open a new one whenever you have a project you are unsure about. It is usually best to talk repair projects over when you've taken a look but haven't yet made a move to fix whatever it is. That way we may be able to reduce the risk of doing something that turns out to be unhelpful, and makes a straightforward repair into a more expensive exercise. Of course the more projects you have completed successfully, the less help you need on the next one, but there is no need to rush into going it alone.
