The Center diff. leaks :-(

Did the sanding, I know I got all the burrs off. By the way it was sitting off the car (on it's side with resting naturally)......... the leak I have no clue where it came from, but at this point it has to be that damn gasket.

Anyone have a part number for these? I can't remember the models you can use. Kyosho / Mugen? Yes, I know that associated has the new clear gasket if you order it right from the manual, but I kinda wanted to grab it locally and not wait on the shipping and wanted some options.

Thanks guys.
