Is this flywheel still good? (pictures)

[klaucke]

Guys, I obviously have my flywheel, clutch and pressure plate out. The clutch and pressure plate look fine to me, perhaps a tidbit of glazing on the clutch I am going to clean up w/ some emory cloth.

However, the flywheel has be a bit worried. It is a bit blue. It doesn't appear to be warped at all, although I'll check it w/ a micrometer and some feeler guages if the experts here weigh in that it is "iffy."

The car drove fine before hand, but I'm replacing the transaxle and rear (front in this case) main seal so I might as well make sure everything is in running order. The clutch felt fine, was smooth and even in engagement.











The last picture is another flywheel I can remove and use, if the current one pictured multiple times above is deemed inappropriate. I realize the spare pictured has a bit of surface rust, but does it seem to be a better alternative?

Your input is greatly appreciated.
