A P swap requires a dist with minimal bushing side play (& never hurts to shim the axial end play to .005" at the lower collar). As you know point dizzys wear more from the flat spring tension over time. AutoZone has em for real cheap or Lowes has the bushings and a 15/32" to 17/32" adjustable reamer is needed to size em (~$20 at Grainger iirc) to fit
