Anyone have that LITTLE tidbit of info missing from the GM service manual and others for the gap between the stator and rotor above the pickup coil? It appears GM decided not to add that info and just say to spin the shaft to ensure the teeth do not touch.

I think they left that out because it does not matter, but how about .030"?

Actually, the gap works out to about 0.006" 3 measurements between opposite points on stator to determine base circle...adjustments to equalize spacings if the stator is bent during removal. 3 measurements on opposite rotor points to determine the base circle. Base circle diameter 1 and 2 differences divided by 2 equals target gap. Create a spacer ring from paper and slip over the rotor. Slide the stator down and tighten the 3 screws. Remove paper. Test spin. Install the distributor and set to original marks made at removal. Tighten the distributor clamp. Install the ICM, connect the new pickup coil, install rotor button and distributor cap. Fire it up and check ignition timing. Enjoy the test drive!

Total time from start to finish with parts at the ready...45 minutes plus 10 minutes digging through book and posting original question.

Did you remove the stator from the shaft? And if so, why?
