Put a timing light on it. If it's the distributor the timing mark will jump forward and back as the idle speed changes.

If the distributor play you're noticing is rotational play of the rotor that springs back when you release it your stretching the centrifical advance weight springs and thats normal.

If it's axial or up and down play of the distributor shaft it's probably the fiber shim on the distributor shaft under the centrifical advance plate has gone away. They all do after time and alot of miles.
The shim under the distributor gear may be worn too. There is also a screw under the dust seal in the distributor shaft below the rotor that should be tight.

If it's lateral or sideways play of the distributor shaft the distributor probably needs to be rebuilt with new bushings or replaced.
