Yes, you can run points with a PMA.
On the 80 up TCI ignitions, it uses a magnet in the alternator rotor to trigger the pick ups mounted on the stator.
To install the PMA you remove the stock stator and rotor. This removes the magnet and pick ups. With out these parts the TCI doesn't work.
No matter what ignition you use, use a key to lock the PMA flywheel to the crank. Then properly mark the TDC, idle and full advance marks. This way when you replace the points you will have timing marks to do the job with.
With out a key the PMA flywheel can slip on the crank and any marks you make will be wrong the next time you want them.
