Fuel pump bracket bolt size & thread

hey guys,

I lost the bolts to my fuel pump bracket - the bolts go into the captive nuts in the trunk, so I can’t bring it to the hardware store to match them to a bolt.

Does anyone know what the size & thread is off hand? Or would anyone mind pulling one of the bolts to check? I’m assuming it’s a fine thread, maybe 5/16… but not sure.
