Expansion Tank Internal

There is on my 73 to pull back into the radiator and the other side of the cap has a
over flow tube on the outside but not on the inside so if the tank fills up it can escape.

I don't care if its stock. I have an aluminum rad, no rad cap. A line to the expansion tank that has a 16 lb. cap that would, if required vent to atmosphere. My question is should the pick up in the tank that connects to the rad have a feed tube to the bottom of the expansion tank?

The car is a 1969 L68 (427 Tri). I believe it to be functionally correct.

there should not be any feed tube to the bottom of the tank. The tank is higher than the radiator, as the fluid expands in the radiator it goes through the small hose into the tank thus the radiator is totally filled with fluid, no air pocket in top of radiator. There is a fill line on the tank about half way which is the level when cold. Looked at the pictures and am somewhat puzzled. Dont you have two small necks on the bottom of the tank? If so are they connected inline to one of the heater hoses? The small neck on top of the tank should have a hose going down for any overflow.

That style of tank should have two connections on the bottom:
The connections are essentially spliced into the heater core hose.

Ah. You're trying to force a round peg into a square hole. That's an expansion tank that you're attempting to use as a coolant recovery tank. Won't work.

What if I Bubba a tube so the into the tank will pick up from the bottom?
What if I leave it as is?

Order the assembly instruction manual (AIM); make the correct plumbing connections shown in the AIM; and your tank will function as it was intended.
You would not need to Bubba anything.

The tank
You dont seem to be clear on how the tank functions. The bottom pipes should be connected to the appropriate size heater hose and putting a tube in the tank will do nothing.
