correct filler neck for 70 swinger 340?

car had wrong gas tank.....replacing it with a non-vented one. the one that was on there had a single vent at the top front center.

but I suspect it also has the wrong filler neck on it.

this is what is on the car now. the tube went through the trunk seal into a hold in the frame section of the car.

But is this one the correct one for a Non-Vented tank?
