Not that im aware of off hand...im sure I could find 1.
"problem is whne the flywheel gets thinnerit affects the clutch pedal travel. Sometimes the clutch wont disengager when the flywheel gets thinner" is his stated concern
Ok, possible the FW may be out of spec. Maybe mechanic measured it. (that would be a first )
If that one you found is legit, it's a good price. These beasts are heavy and expensive to ship. The rusty one I wouldn't touch. Plus that ebay seller has a few negative feedbacks.
However, if it's possible for you to take your existing one to a MACHINIST who knows these things, and take the relevant pages of the FSM with you, it won't cost you anything to have it checked. Otherwise, count on around $300 to have a good, machined one shipped to your door.
