Difficulties Installing ABS Headliner in 73 Swinger

As Jpar suggested, make sure it’s tight against the roof before you start trimming it back. Installing the dome light will help, pushing it up into place and then clamping it will help. It’s hard to tell from thr pictures but it looks to me like it’s not pushed up against the roof along the edges, it stays flatter as it transitions from the roof to the edge leaving a gap behind the headliner. You want to push that out before you start cutting.

Yes, they’re expensive. So are the replacement cardboard ones, and they absorb moisture. Yes, they need some trimming to fit perfectly, but that’s true of darn near everything made for these cars. Which is why I suggest getting them without any upholstery. The other reason I suggest getting them without upholstery is that the glue they were using a couple years ago wasn’t great, and I had to re-glue pretty much the entire headliner fabric on mine after it separated in the heat. So yeah, they definitely have their issues, and at full price I can see why some folks would be disappointed.

I still like them far better than the cardboard or the earlier fabric headliners, but that’s just me. The last one I bought for my Dart was from amazon and it was on clearance for way less than half what they usually sell for, so deals can be had. All the interior stuff for any of these cars is insanely expensive. Legendary’s stuff fits well, but costs an arm and a leg. PUI has plenty of complaints and issues, and they still cost a heck of a lot of money. Just less than legendary. For me it just boils down to I’m not doing custom upholstery myself. Not what I want to spend my time doing. Could I make something cheaper? Sure. Would it look better? Probably not. And it would take forever. That’s why I spent the money, and it’s why I tell other people the issues I had so they know what they’re getting into.
