Radiators (copper and brass) with fill caps did not use surge tanks. Cars with radiators without a separate fill cap (aluminum) used surge tanks. The car in your pics has a copper/brass radiator. You should not have a surge tank.
The AIM page you cite in your other post refers to base model production only. Your copper and brass radiator indicates you have optional AC or AT (or both). Either option took you out of the definition of base model. Either option required a radiator change for your car in place of the base model aluminum radiator.
The owner's manual says to fill your radiator to about an inch below the bottom of the fill hole. That space allows for coolant expansion.

thanks for the reply Easy Mike !
would you suggest then that I put a length of hose from the radiator down to bottom of engine compartment in case it pukes out a little anti-freeze ? Knowing that if I fill it correctly, I shouldn't have this problem anyhow...
I looked up in the receipts too, the radiator was rebuilt, not replaced.
thanks,
Scott

There should be a hose on the nipple under the cap. If it burps, it directs that little bit of coolant down so it won't (a) get all over your nice clean engine, and (b) won't stink the place up.
