              19.5mm is 'L' on this pic, I can't remember if flywheel bolts have an unthreaded section.

                  aye, sounds right mate.

                  B cold be the loctite`d section, again proportions would be correct

                  i do loads of flywheels on fleet stuff so looks about right

                  Cheers everyone
