After many years of supporting gas imports into the UK, I have finally found a sensible use for the AGA which adorns our kitchen. Just the right temperature for heating a J2 flywheel ring gear!
Lucky you! The P-type ring gear, of course, is made integral with the flywheel and has to be machined off. I'm now searching for a good machine shop (in Minnesota) to do it. The last time (different car) it took two years to get my flywheel back.
