I messed up my lower control arm bushings huh?

I just spent half the day cutting the outer sleeve of the old bushings out of the lower control arms. Then I pressed the bushings into the control arms. After that I remembered this page saying you'll ruin them by doing them that way because you can't just press the pivot shaft in there without ruining the rubber.

Since I already pressed the bushings in, I have to remove them, buy a new pair and press in the pivot shafts to the new bushings before pressing the bushings into the arms right?
