94 Grand Am factory CD player?

Does anyone out there know specifics about the factory stereo for a 1994 Grand Am SE? I'm wanting a factory AM/FM stereo with in-dash CD. I have found plenty of GM CD stereos for appx. $100-$150 online, and in junkyards.
However, I'm told that for this particular year Grand Am, I have to get a model/year specific stereo, and these don't seem to be plentiful, or always cost a lot more.

Does someone know if the CD player from other mid-90's GM cars will fit, and mount up properly? Would the cd from, say, a '95 Grand Prix, or a "94 Beretta work?

Thanks in advance for serious replies.
