My Harmonic Balancer Fell Off - Help!
I decided to drive the Vette to work today. As I was pulling into the parking l my power steering went out and I heard a thumping sound - I figured the serpentine belt had broken. I parked the car and popped the hood - the belt had come loose, but was OK. I started looking at the pulleys and all of them were in line except for the harmonic balancer - it was jutting out about 1/4". I figured the bolt had slipped or something and I'd just fix it after work.
Well, after work I had planned on tightening up the bolt or just banging the balancer back into place with a hammer. However, when I put my hand on the balancer it just fell off.
Here are pics of it and the bolt:
As you can tell, the bolt was stripped pretty badly. The bigger concern, however, is the inside of the balancer - it's rounded out completely. It slips right on and off the crank without any resistance. The crank itself has some scrapes on it from where the notched edge of the balancer rubbed against it.
Any ideas on what could have caused this? Do you think I could get away with just using another balancer and helicoiling the crank bolt hole? Or does the crank probably need replacing?
Thanks for any input.

No advice, bumping the thread for you and seeing if a new post can get past the hanging problem with opening the threat.
