Steve, I recently bought a headliner with ABS backer from Mike's Monte's. Very good quality and great color match to my new burgundy carpet and interior trim pieces. I do have to slightly trim the front edge. Probably because I may have it too far forward. Looks like I will have to slightly trim the sides maybe 1/8 - 3/16 inch. But I would rather have it slightly larger than be too small. I would definitely recommend a Mike's Monte's headliner.
