Unless I missed it in the package, I did not get any welting. I ordered it from Chad.Airtex seems to be in a better position to make something for you than Flightline.
Did you get your headliner from Airtex? Did they give you enough of the welting to go all of the way around the greenhouse opening? My kit only had enough to go across the back and when I called to ask about it, the guy was a bit dismissive. The new method is to go all of the way around so I had to call back and order more. Didn't leave me with a good feeling about Airtex.
Got headliner from Airtex. No welting.You ordered the headliner from Airtex or Chad? Was there welting lining the greenhouse opening at the seam between the glass panel and the frame?
