67 harmonic balancer

How do I know if the harmonic balancer is shot. The 67 harmonic balancer is a 2 part setup, 3 if you count the spacer. The part of the balancer that sits inside the pulley has an inner and outer donut and there is a rubberized divider between the two. And I can spin it the outer donut around the inner part. Is the rubberized piece shot and worn out or is it suppose to spin. Meaning I need to buy a new harmonic balancer.
Thanks

You will need to buy a new one, it should not spin. All 3 parts should be bonded together, inner rubber, outer .

If you can move it at all, it's toast. Don't run the engine until you've taken care of this. You're taking a huge risk with your main bearings if you do.
