In your specific application a 'normal' style HT bolt might suffice, but the OP is asking where he can get suitable replacement bolts from and some of the advice offered here is just misleading, especially if, unlike yourself, you may have little or no knowldge of fastener technology.
Of course a 12.9 bolt will have sufficient shear strength to do the job.
But this isn't about just a matter of obtaining a piece of metal with a thread on.
As can be seen from the picture in the link I posted the OEM flywheel bolts have a flanged head that don't require a washer to fit. They also have a plain shank offering a better location through the flywheel.
That is a different thing to a common or garden high tensile bolt from Joe Blogs that will most probably be just a regular plain hexagon headed set screw that should be fitted with a washer. Not just any old plain washer, but a hardened washer.
In which case a flywheel bolt really isn't just a bolt like any other.
Just saying

Completly agree, I forget that I deal with stuff like this on a daily basis, so its just second nature to me!
