72 Demon Sill Panel Placement

Hello I'd appreciate some help I've got a 1972 demon that I am replacing the cardboard type seal panels along with the headliner which is going to be the ABS headliner my question is how do these cardboard panels attach to the body of the car if you get my drift and does this panel go under their rear window gasket or on top I would really really appreciate some pictures of what you guys have so I can follow suit thank you very much in advance
