72Duster front swaybar bushings

Hi guys, I recently purchased a 72 Duster 340 and was replacing all the suspension bushings, balljoints etc and started on the front swaybar. I am not sure how to get the old bushings out without destroying them (not worried about that except that I am not sure how to get the new ones in without destroying them!!). I was thinking that the bushings and the metal loop that goes around them would need to be lubricated and the bushings possibly heated in hot water to make them more flexible. Anybody have a method that works? I was just going to buy a set of bushings and endlinks from Classic Industries.
Thanks for your help.
