I was that custom auto sound sells a replacment truck type speaker that has the edges cut off so I was thinking that might work, then I thought just regular car speakers would work, it looks like a standard size. I just havent gotten around to taking one of my grilles
down to best buy to see if it would fit.
If neither of those options werent going to work I was going to either cut down a truck type speaker or unglueing and reglueing the paper from a good truck speaker to my blazer speaker metal piece.
