No balancer just a flanged hub.

Flange behind the pulley

Not sure about the noise unless its split and is vibrating/rubbing.
You can post up down in the wanted section if you need that specific part.

Here is a CL Ad that has some nice parts on it. I don't think your that close but I'll post it.

Since there is no harmonic balancer, and it is a flange secured by a center bolt to the crankshaft, there would be no reason for this particular component to make any noise whatsoever, unless it was not properly installed and improperly secured to the crankshaft. If your engine was properly maintained, you should hear no abnormal noises, such as a rod or main bearing knock from your engine, except for the normal clicking of the rocker arms, due to the fact that these engines were equipped with solid valve lifters. Any other abnormal noise coming from these engines would indicate a more serious problem.
