1968 340 harmonic balancer and main pulley

Sorry for the misinformation.
Whatever, I have on this set up, I’ve been running for 2 years. So, it must be an internally balanced harmonic balancer. However, the last two mechanics that have worked on car were pointing out that something must be bent or something, recommending that is should be replaced.

It does wobble and does not look smooth and straight as other period cars I see.
