With regards to a 928 clutch, I would not replace anything untill it is completely screwed. It is the work of 1 1/2 hours to remove a clutch from a 928, you can do it yourself, and I'm sure you have a thousand things on your car where the money could be better spent!

Leave the clutch well alone and fix things that are not working, first.

Don't worry about the ring gear, when an engine stops, it generally stops in the same position every time,sometimes more than one but always in distinct positions, thus when you restart it the starter engages in the same place every time and slowly the teeth on the ring gear wear in that area, after 30 years the teeth look like yours, I reckon you should be right for another 60 years at least! I've not had a flywheel off, can it be bolted back on in a different orientation? thus moving the worn teeth away from where the starter engages.

Most manufacturers will unequally space the flywheel to crankshft bolts to ensure that they are not bolted in the wrong orientation if it is critical.

Good luck, I can see that sorting the sense from the nonsense on this forum is going to be one of your challenges for this resurrection.

Cheers Roy
