I will be replacing my Torque Convertor, Pan, Gaskets, and Filter. What is the stock type fluid used for a '79 TH350 Automatic? I'd like some idea's on a NON-synthetic performance ATF. I don't think there is a need for synthetic. I'm cruising, not racing. ;)

Dextron is GM"s fluid of choice..
I believe Dextron III is what they are using these days

Dexron III is GM's choice for lubrication and quality. Bolts are usually 3/8 standard coarse thread and 1/2" long. Some years had metric bolts not sure what the specs for those are.
