Looking for part information

I am looking to break down a few vehicles I have and sell them for parts. My question...is there a simple way to know what years a part will work with. For example, I took my radio out of my 2000 dodge truck, how do I find out if that same radio is good for a 96 97 98 99 2000 2001? Also any advice on items that tend to be the best $ from most vehicle would be helpful.

Thanks
Jay
