I'm up for more discussion!

The "internal" distributor operations (describing the axial rotation of the reluctor ring past the pickup/trigger that will send the signal to the ignition module to discharge the ignition coil), are part of my assumptions. Although, GOOD LUCK finding a distributor from parts store "X" that includes:

1. True axial rotation about the shaft's center
2. Unworn, perfectly constructed reluctor
3. Pickup/trigger in plane with above mentioned reluctor
4. Mount surface on rotor button in plane with mount surface of dist cap
5. Available dist cap with mount surface in plane to cap contacts (or uniform contacts for that matter)
