Rotor/Reluctor Phasing Question

That sounds like a plan, however double check rotor to #1 plug terminal.

If the VR curve is flipped the - to + zero crossing lies in the nearly flat part of the wave about 40 degrees from normal. A typical rotor to terminal span, is about 40 degrees, so it is possible, there may have been a shift at the cap terminals, to get it running. Timing may have been uncertain, because triggering on the flat zero crossing varies with noise, and other undesirable variables.

Good luck, you will like the difference.
