The rotor should turn a bit under finger pressure, but should not move side
to side without turning.
If it does move side to side, then a new bushing in the distributor body is
called for. Replacing the bushing is about a "3 wrench" operation, it can
be done at home but isn't trivial. I'm not sure if bushings are still
available from the big 3, they weren't at one time. However, the bushing is
a standard id and od; it should be possible to replace it with two stock
bushings from McMaster-Carr or wherever. You might have to cut one of them
to length.
Another alternative would be to just buy a rebuilt distributor, or have
yours rebuilt. Check with your local auto electric shop to see if they can
rebuild yours.
