When the rotating assembly was balanced, quite a lot had to be machined off the late model AOD flex plate so I suspect the HB is a 28 oz, but can anyone confirm? Is this a 28 or 50 oz balancer? On fitting it, there is wear in the keyway so I need to replace it. The engine is a late '79 block, AOD & flex plate are from a late 80's car. Photos of it below:
