Excess runout on flywheel

[Al 29Tudor]

Good afternoon all,
Today I mounted a dial indicator to the flywheel housing to check the run out of the flywheel.
It is .017 and Les Andrews states .005 is max run out.
What are the implications of this condition?
I've put 15,000 miles on the car over the last six years but took it apart to stop the transmission from leaking and try to determine the cause of clutch chatter.
Please let me know if you've experienced this and if you corrected it.
Thank you for your help.
Al
