1973 Duster headliner question

sounds easy enough, i was just worried that it would wrinkle on me.. i will give it a try... while i have you guys, i have another question, my 73 duster interior was mising a lot when i got it, im not really sure what im talking about but here goes, is the a long metel trim piece that goes along each side of the cars interior to trim out the headliner?
