The sale on my 533 flywheel fell thru as it wasn't in as good of condition as I thought it was. Upon closer inspection it is in fair to poor and needs a resurface. It might not even clean up 100% with a surface, but it will be good and fully usable IMO, I would not have any qualms about using it on one of my cars, again, after a surface. Still, it's a lightweight flywheel so I'd like $100, shipped.
