area 51 m17xr1 not M17x command center help please

I have the alienware area 51 m17xr1 model that was pre dell. the hdd finally died and I had to load widows 7 on it but I'm having a terrible time finding the command center for my model. Ive been reading hundreds of forums even went as far as calling the alienware tech support which refused to help me now that they're owned by dell.
unfortunately the links to every command center for my model on this site are no longer being hosted. Can someone please post a new hosted link to this?
