I cannot come up with more than .01mm difference on both rotor housings using the top - spark plug difference method.

Happy Day.

 

That sounds healthy!

 

I am learning.
Bought a set of micrometers because I did not trust the digital caliper and wanted a second opinion.

The mics are in inches so I had to convert. (Gotta love Google)
I kept reading the same two spots on each housing until I was getting consistent readings.

The one housing was 2.7550" (69.977mm) at both positions.
The other housing was 2.7550" on the top and 2.7545 at the spark plugs. Or the difference between 69.977mm and 69.964mm which is .006.

Yes, I think the housing will be just fine.

Thanks again for all the help.
