Not sure this helps, but here is a photo of the attachment method on my Proz Bi-Fold. The cover uses a black track that sits on top of the utilitrack. The black track is held in place by three brackets, 2 of which are visible in the photo. The tonneau cover then attaches to the black tracks. Not sure if you're swingcase would interfere with those. I do like the tonneau cover -- there are a few more photos on this post: ProZ Bi-Fold Cover.
