This company can fix you up no matter how you make a change. Contact "Adrian"
Others would be ... give C&H a ring.

NGK BPMR6F if your engine will accept a tapered seat plug .... and most will. There is a washered equivalent but I don't have that #. These plugs fit the 5/8" caps perfectly. Ralph Cunningham put me onto these years ago and I never used a 3/4" plug again.
Edit: NGK BPMR6A is washered version.
