Alero equivalent

Hello,
I need some parts for my 2004 such as defog/ant module, and a couple of spare bulbs. I heard that ether a pontiac grand am or grand prix have interchangable parts. Is that correct? I am visiting a junk yard this weekend and if they are out of aleros like they were a few months ago, then I need an equivalent. Thanks

Tom

The RF filter module for the defogger is the same in the Grand Am. And many of the light bulbs or lamps are the same or shared.
