The vibration is likely a flywheel/clutch out-of-balance situation. It could be as simple as a portion of the friction disc loose, or as serious as a cracked & separating pressure plate.
If the original trans was an automatic, the manual flywheel may not have been match-balanced to the autobox flywheel.
Thanks Frank, I was also wondering about the flywheel and clutch. This was always a manual car, so no swap. However, I need to go through the service records and see if the clutch was replaced and when. They serviced at what seems like a reputable shop.

I should say though, the clutch issue feels hydraulic to me. And, the vibration doesn't ramp up with vibration like an out of balance flywheel. It does smooth out at certain RPMs
