!968 Control arm brushing replacement

[hearnold1968AMX]

I'm starting to restore a 1968 AMX and have been trying to replace the upper and lower control arm brushing. I have the control arms off, but can't seem to figure out how to get the old bushing off and the new ones on. Is there a trick to this? I got new brushing, but should I replace the washers as well?

Thanks,

Howard
