The Stovebolt Site Forums The Shop Area Making a Stovebolt Bed Tri fold covers for an AD truck bed

I see all the new vehicles have the either trifold or double fold hard covers and I wondered if either any of them will fit the 54 and up step side boxes or if they make them .The ones I have seen have been custom made and are way up there in price.Has anyone adapted one of them to fit . I have one on my Toyota truck and it looks like it can be cut narrower .
