Mopar A-Body Gas Caps

OK a 70 tube and I see it is a newer cap.
I guess the real question is since the car is a 925 build is the tube correct for my car? I have to look again but I'm 99% sure I don't have the 71 one year tank also.

The tube in the trunk tells me you should have the 71 tank for CIP/vent.
