cross shaft bushings

[1930artdeco]

I am in the process of rebuilding my entire brake system apparently. So I was poking around and I noticed that the brake cross shaft moves up and down and for and aft. After researching here and in Les Andrew's book I learned that it should not do that. I also learned that to replace the bushings correctly I need to drill out the pins, remove the arms replace bushings and reinstall arms with new pins.

I also read that some people have used the new split bushings to good effect. My questions is can someone tell me how to get the old ones off to install the new ones? Which grease/graphite should I use? Are the split bushings the same as the original style? And if not can I get an original bushing and cut it in half and use it like a split bushing?

Thanks a bunch,

Mike
