Hi everyone

I've searched for the past week all over the net to try to find the bolt sizes and lengths to attached the serpentine brackets to L31 sbc.

A little context, I have a 72 GMC I am swapping an L31 5.7L into. I have all the front accessory brackets, pulleys etc but I do not have the bolts that attach them to the front of the block. I amm astounded I cannot find this info on the internet or even a kit.

I think they are 3/8" but lengths is what I need. Can anyone help me out?
