Well Savage, I taint GOJO, MOJO, HOJO or Tom, but I do have an opinion and here are my thoughts on the AD headliner. Mine is the original and it to is saging. Even so, it's in real nice shape. I would think that the warpage could be flattened out if you wet the material and weight it down for a week or so until it has a chance to completely dry. However, I think the bigger problem is that the material has also shrunk over the years and no matter how flat you get it you can't make it any bigger. And that in my opinion, Can't be fixed.
