What size differential

[Iluvatar]

I know it's gotta be on here somewhere but I can't find it. I searched and pulled up every thread under the sun.

What size differential are in a stock 99 Cobra? Are they the same size as a 96 Cobra? I went to buy a new gasket and all of the local places only list up to 96 on Cobras for some reason.

Thanks
