Looking at the diagram they should be but the modules have had quite a few modifications done to them and if you don't know the history then its quite possible there could be some differences due to somebody working on it.
You also could have the earlier 1998 version so your question is too open for me , you would really need to check each modification on the 1999 version ( if that's the one you have ?) so all I can say with not enough identity supplied is --yes they should be.
