Others will post soon and should be able to provide dates and corrections.
Pre-verto cars came first and on factory installations would have used an inertia starter with a 9 tooth pinion gear. The verto cars came later as did the pre-engaged starters. I believe those had 10 tooth pinions. Others will have to confirm when the verto and pre-engaged starter transitions happened.
I have never seen a gear reduction starter that is not "pre-engaged". Pre-engaged basically means that the solenoid is mounted on the starter. When the solenoid fires, first it extends the pinion gear into the ring gear. At the end of that stroke the power contacts are closed which allows the starter motor to start turning. It is "pre-engaged" because the pinion engages the ring gear before the starter begins turning.
I suggest you remove your existing starter and look at the flywheel ring gear through the open hole. Try your best to count the teeth and notice whether or not the teeth you see have a lead in chamfer around the tooth profile. If you see a chamfer the ring gear should be expecting the pre-engaged starter with 10 teeth. The tooth count should confirm this. You can compare your observations with the starter motor descriptions for our host's products to confirm what will work. Then compare that with the description of the gear reduction starter you are considering.
