The defroster grid will already be on the hatch glass when you order a replacement hatch glass with defroster. I don't know what the availability of one is new, but 7 years ago I know it was. I have seen some on ebay, but usually pickup only. 2 if my grids stopped working within 2 years and Ford never did get them fixed with the paint on grid stuff. But some rear defroster is better than none. Although, I am sure I could live without it.
