I'm going to install my first headliner 1965 Dart

This sucks! Working with my hands overhead....No wonder people farm this stuff out.
My bows seem to be fatigued. I'm guessing that they are supposed to rest against the underside of the roof skin? I have had to pull stuff back out and rebend them a couple of times. I'm also guessing that they are supposed to be straight up and above the pockets in the sides. If the headliner sleeves are not exactly to the proper length center to center, this is a problem.
Wrinkles are not a concern yet, I'm just trying to get the bows to get into the correct position.
More tomorrow, maybe.
