Flexplate is not fits the torque converter

Hi, small update.
I've changed the torque converter for 10 inch bolt circle, flexplate also changed to "stock" ATP-Z332 with the one hole extension. As the result - vibration became significantly lower, looking at an engine you'll never notice that. but, it's still there. on the parking mode - it's minimum, in drive - it's almost zero, on the road - in the middle rpm it's noticeable. So, right now I have stock front damper, stock flexplate, but still vibration. My next move could be to remove an engine and to balance the crankshaft and the damper and the flexplate and the torque converter all together.
