I was wondering, would a 2001 am/fm/cd stereo radio fit in my 91 ls?
The wiring in the radio will work, but i am not shure if it will bolt up. If it were me i would just go out and buy an aftermarket cd player. 
I was wondering the same as I want a nice, clean, simple cd player. This seems to be the best bet.
Anyone know if it will work?

Yes, it will bolt up. The plug on the back is the new style so you will that harness plug also.
