Do you still have the piece?
ABS plumbing plastic adhesive is what most use. There is a black available.
There is also some special stuff too.
http://www.polyvance.com/PlastiFix-Kits-1I still have some saved ABS plastic from the front of my IS. You can also get some ABS pipe, cut in half, and put it in the toaster oven, and let it heat up and melt flat. Now you have some raw material to fix the part.
Also the holes that haven't broken yet, make some washers and glue it on the inside of the lid.
A link for what I was referring to.
