Stereo & Electronics - are the cd player mounting brackets the same from 93-97 compared to 98-02?

just got an aftermarket cd player that is off of a ls1, will it go on my lt1 ok? if not i have another one that is off my lt1.. but dont want to take the time to switch them if it is not needed.. so my question is do the aftermarket cd brackets work on all 93-02 fbodies or are they different?
any help is appreciated
