66 Barracuda headliner install problem

Thanks for the feedback. I checked the position of the bows compared to the seam dimensions and something is definitely off. The headliner is about 3/4" to 1" too short. Back to Legendary for a return...
I did get the insulation from Legendry also and installed it. It can become mouse nesting material. The whole reason I'm redoing the headliner is the one I installed 20 or so years ago was a nesting area for mice. I could see holes in the headliner and stains where they died and met their maker (yech). If you have a mouse problem you should take care of that. There is all kinds of damage they can do once they get in your car.
