360 engine vibration

I'll check again, tonight. Remember I dont have next day delivery for parts, so I'd be twiddling my thumbs for 2 weeks waiting for the damper to arrive. I need to be 100% sure on this is the problem I'll video the crank DTI check and video it end on close up whilst cranking. I have a small lathe at home and if the damper will fit in it I'll video that and then try it back on the crank again.
