Flexplate hitting starter

[Nodnarb76]

I'll be as thorough as possible.
A year ago I had the starter replaced. The it developed a knocking sound, turns out the Flexplate was hitting the starter because the whole Flexplate/torque converter was wobbling.
Ended up not driving it much for the past year, then had the Flexplate and torque converter replaced. Found the snout on the torque converter was broken. Probably causinfpg the wobble.
Once everything was back together and started, it still knocked even though nothing wobbled. Even after hours of shimming the weight hits the starter every RPM.

I have worked as a service advisor for 14 years and any pretty competent when working on cars. I'm having the techs at work do it for me though, I know when to let the pros do something I'm not comfortable with.

Any ideas?
