If it looks like a rubber one it is, they have both!.. Some struts have a lip that prevents the bushing from going forward, the outer part of those are brass so it will take a bit more effort to cut it, just watch how far you cut when you get close take a small chisel and tap the edge it should colapse if your close, if not cut some more. When you put the new one in, before you cut it in half draw a line down the center and when you put them in make sure you match the lines, most of the time those fibre bushings are not bored dead center and it can be a real bitch getting the shaft to slide up!..Hope this helps!...
