Lower Control Arm Bushing Sleeves

Now I'm having a heck of a time trying to get the outer sleeves out of my lower control arms. The manual says to cut them with a chisel. Then I got some instructions in a kit from Mancini racing to weld a washer onto them then press it out. I've tried both. I was wonderin if anyone had some other tricks to get those old sleeves out? Any help would be greatly appreciated.
