Difficulties Installing ABS Headliner in 73 Swinger

Did I mention that the re-boot was the best advice I saw on this thread? One needs to approach this task in the same way as putting headers on an A body. #1 rule, stay calm and think.

All in all the Rock Auto headliner fit very well. We had a little trimming to do up front in the corners by the a-pillars to get it to sit correctly under the windshield gasket but I think it was more of an issue with the gasket rather than with the headliner. Here's my short step by step. We started at 8 AM and had it in by 9:30 AM. Definitely a 2 person job.

1. Stay calm
2. Remove the small clip in the center of the back glass.
3. Position the headliner to the back glass and have your helper work it under the gasket while you shove. Use the dome light hole for leverage while pushing. Working from the outside into the center worked best for us while fitting into the gasket. Don't forget to pull the dome light wires through the hole.
4. Stay calm
5. Hold it in place with the shoulder belt bolts
6. Stab the dome light in (Loose but started)
7. At this point your helper shoving upward can relax. The headliner will stay.
8. Stay calm.
9. With a flat poly / plastic trim tool work the windshield gasket over the headliner staring in the center and working out. Once you get the center 12 inches or so worked in, stab the mirror bracket. Loose.
10. Work the gasket out to the corners and stab the visors. Loose.
11. Stay calm. (Which is easy at this point)
12. Pop about 12 inches of the rear gasket out and re-install the center clip and zip the gasket back up.
13. If all is positioned well. Tighten everything up and install the rest of the trim.
14. High five your helper because it's in.

From here on out it's just a matter of popping in the trim pieces and tucking into place.
No $hit, 1.5 hours.

I hope this helps someone.
