'70 swinger TTI exhaust ??

I had factory tips on my Dart Sport (see pic). The TTi tips are slightly more square than factory, but not that noticable. Also, TTi tips have "TTi" ecthed into the side of them in small letters. If you're restoring a car to factory specs then go with the factory-style tips. Not sure if Year One tips will fit but it should be a simple matter of the tail pipe size.
