What size vibration damper bolt head do you 356 owners have?

The head size for the 356-ci engine's vibration damper bolt, #341404, 1 3/4 inches, is listed as 1 1/8th inches in both pre- and postwar Packard Parts Books. This mistake was never amended because, a rarely changed or addressed part, no Packard serviceman brought it to the attention of the shop foreman, who in turn alerted the zone rep, East Grand Avenue.
