1979 chevy 305 torque converter bolts?

[Jesse M]

Hello...I was hoping someone might know what size the (3) torque converter-to-flex plate bolts are for a '79 chevy 305. I seem to have lost them and there isn't any information out there for bolt specs on engines! I feel bad for guys who have to build these things without already having all the bolts on hand. I'm also having problems with bracket locations for the pulley system, and freeze plug locations. I ended up with a handful of "extra" freeze plugs and pipe plugs. Can't seem to find where they go...also two things you won't find specs or diagrams for
