On my 63 Avanti (289)   I have a opening about 1 inch in diameter that appears to be threaded, it is located about 3 inches in back of the Oil drain plug, can anyone tell me what 

this is for ?  Thank You  ( I'm working outside under the car, no garage)   Old Tom

Sounds like it may be the 1" opening (hole) at bottom center of the torque converter housing provided to access the torque converter drain plug.

Is this on the oil pan itself?  A picture would help a lot,,,

Nope, it's at bottom center of bellhousing, around 6 inches to rear of oil pan drain plug.

Isn’t that the access hole to drain the torque converter?

Should this opening have a threaded insert ?                 ( is Not on the oil Pan itself )

No......it's just an open 1" hole.
