360 engine vibration

I'll be buying a new bolt and washer with the damper. The damper is a tight interference fit on the crank and needs to be pulled on with the bolt and pulled off with a hub pulley. I've checked the damper with the DTI when partially seated too and its the same amount running out of true, that's what got me on path of a manufacturing defect. Anyway parts on order.
OK, good, just checking.

For example the $68 damper by the time its gets to my door has cost $195.
THIS is the 'good grief' part IMHO.
