I agree on the measurement method, much more accurate than the torque translation method.

I haven't bought any rod bolts so I don't know the stretch spec for sure, but I read in one thread the spec was 11.5-12 mils (1 mil = 0.001"). From what I understand, the accuracy of most dial calipers (0-6 inch) is +/- 1 mil. I don't think I would want to be using a dial caliper if that's the case.

Plus, not only are you fighting the case to get the tool in there, the micrometer should provide more consistent, repeatable readings.
