Crank Pulley Bolt Length?

[Ceddy]

Anyone know the length of the bolts for Crank Pulley/Harmonic Balancer?
For a 6-Bolt if that matters.

Searching I found they are 8mm x 1.25 and are torqued to 18ft/lb.
But can't find their length anywhere.

Thanks.

Haven't found length, but they call for 22 ft/lbs

I just ended up buying some 20mm long.

Still don't know how long they are suppose to be, but with 20mm at least I know they won't rub anything behind the crank sprocket.

Thanks for the replys.
