70-71 dart fuel fill tube in a 72 dart?

[swingingdart]

I'm trying to find a new fuel fill tube for a 72 dart, but all i can find for sale is 70-71. My 72 has no vent lines, does the 70-71 have a vent line? I just want to get one that fits. I also saw pictures of duster fill tubes that look Similar, but surely they are different right? Any help is apprciated!! Thanks!!

From what I understand '71 is a 1 year only part, and nearly impossible to find a cap for.

Duster/Demon/Dart Sport are different. Look for '73-up Swinger/Scamp parts.
