There are many good GM 1-1/2 DIN CD models that can be purchased on Ebay and other places. These should install in the same area, but possibly may need an adapter cable. These are available through most stereo shops. You can often get a premade GM-GM adapter cable [different year ranges] or you can get both ends and make it yourself (about the same cost).
The aftermarket choices are dwindling. IMHO, the best is mine, the Pioneer DEH-P77DH. I bought mine in 2000, shortly after they came out. They often come up on Ebay often. There was a Pioneer Premeir model back then too that has disappeared. There is also a Pioneer DEH-P47DH that is the same as the 77 except for no remote, no built-in alarm system, and fewer RCA outputs. Jensen, Audiovox, and Panasonic used to make one too. These also fit Chrysler cars, so you might try finding them that way too.
You can buy a single DIN unit and use an adapter. Some adapters have an open compartment/shelf/storage area underneath. [My wife has one in her car; she likes to store her glasses in it.]
