Jim,
One needs to isolate the vibration ie drive train, suspension/ wheels or engine.
Note if the vibration gets worse, same or better in the following questions.
1. Does the vibration only happen when accelerating?
2. does the vibration happen when holding a constant speed?
3. Does the vibration happen when decelerating?
4. Is the vibration felt from the steering wheel?
5. Is the vibration felt from the gear shift ?
6. Is the vibration felt more in seat?
7. is the vibration seem to come from the left, right, front or rear side of
car?
8. Is the vibration produced when the car is stopped with the engine revved up
to the proper rpm range?
9. what road speed range does the vibration occur?
This would only be a start to locating the problem. I'm sure that after
answering the above questions the list could better diagnose your vibration.

My son brought his car (1973, unknown mileage, unknown driveline
maintenance) home from school over the weekend and mentioned a vibration.
Sure enough, between 2,500 and 3,000 RPMs in both third and fourth gear, the
car starts to vibrate.

The vibration is pretty much the same. Thought we would have the
wheel balance checked first, but I believe the vibration is drive line
related.
What do we need to look at next? What do we rebuild/replace first.
Thanks in advance,
