82 Toyota Pickup Second Pulley on Harmonic Balancer Bolts

[82LeaseTruck]

Once again I am here looking for help determining bolt sizes. I am down to the last of the project and find I am missing the 4 bolts that attach the second pulley to the harmonic balancer. Does anyone out there know what size these are? Your help is appreciated!
Thanks,
Lance

I believe that those will be 10mm head (M8?) bolts - probably an inch long?

Once the diameter and thread pitch is determined, just make sure you get good thread engagement without bottoming out the bolt before the outer pulley is tight.

Thanks for the reply! I assumed they would be the same as the other pulley but those are 6mm and too small. I'll check the 8's. I think these are the last bolts I need to finish,
Thanks again!
