This Forum and the members who participate here have helped me enormously.  There's information offered here that is not in Ford service manuals or service letters.  The Forum Archive of past information shared is invaluable.  Digging through the Archive can take time, but it's amazing what is there to be found.

Hope this helps you!  

Regards,
Charlie Brown
