Well, thanks for the help, everyone. Try as I might, I couldn't get the bushings out. So I took it to a local gunsmith. It took him more than half an hour, but he finally figured out a way to do it. He created a new slot in the soft metal by hitting a flathead screwdriver with a mallet into the soft metal of the bushing head. With that new slot, he muscled the bushing out of the hole.
