The best diagram that I used in a long time. Everything was right on te money. It was easy and fast. Iwoiuld but again when I need a service manual.

Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.
