I honestly dont know. I would guess around 15k. Car has barely been driven

Debating if i should replace. But it felt just as good as new when i pulled it

If it's already of, why not replace it and save yourself the trouble of replacing later down the road.

Call clutch manufactor and ask how thick the lining is new, and or what the service limit is on the Disk.

Got the specs in an email. Ill have it checked out to decide.

Just because its off doesnt mean i have another $500 or so to easily burn. Replacing it isnt that hard. I can yank the engine pretty quick with trans attached. Never tried dropping just the tranny

Can someone please explain or show me where exactly this measurement is taken?

Per comp clutch
The new spec of the clutch disc is .308 inches. The discard limit is .278 or lower

Its well within spec, im reusing it. Is it necessary to have the flywheel and clutch resurfaced?
