If you are referring to the top window seal that goes from the front of the door jamb up and over the door window to the back of the rear side window, Yes, the '71 and '72 non-SE seals are the same as the '72 SE. The glass is also the same just hidden behind the "plug". Now the '73 SE on the other hand is not the same as it has the stationary "opera" window as stated therefor having a 90 degree corner in the seal down the back of the door glass.
Hope this helps.
