I'm going to install my first headliner 1965 Dart

It is just frustrating. That and uncomfortable.
Building engines, you are looking down, leaning down.
Body and paint, you are leaning, kneeling, standing.
Suspension and brakes, I am standing, at least I am now since I bought the car lift.
Looking up the whole time, my neck is sore. With the overcast skies, the room is too dark to see well so I have a headlamp and a drop light in there. Add in the UNfamiliarity and it makes for a pisser of a job.
I don't like turning out substandard work. I will finish but I am not enjoying this task at all.
