Sounds like a mixture of the inner and outer window sweeps. The inners involve the round or flat bead, which is Firebird or Camaro, they always had a bead on the inside. The outside depends on if the door had the large add-on trim or not as to if the window sweep got it or not. Same as inside, there was always a strip on the outside, it was either the large decor strip on door shell and plain rubber sweep, or plain door top/no decor strip and small bead on sweep, which could also be round or flat, for Firebird or Camaro style.
Having said that, your car currently has no bright decor strips around the rear of hood and door tops, indicating you'd want the outers with small bead. But based on your T-tops that have gutters, it came off a car that also had gutter molds over roof and since removed, and these often went with cars with the decor strips too. But not always.
If you do not intend on adding any of the 'chrome' strips to door tops then use this type of sweep outside:

Worse still if you end up with 2 lots of bright trim strips!
Nice looking car and hopefully in safe hands now. Yell out if still confused or any other q's.
