On this vehicle, there is a hall effect vane stator switch that functions as a camshaft position sensor. As far as replacement, the distributor needs removed and taken apart. This is a little bit of a project. Also, an arbor press will be needed to perform the replacement.
Keep in mind, the distributor will need to be reinstalled correctly. The last two pics below are the directions for the removal and replacement of the distributor.
I hope this helps. Let me know if you have other questions.
See pics below.
