Here is what worked for me and I didn't destroy the bushings or replace the full control arm: a ball joint press. FYI I was taking swings with a full size sledge hammer at these bolts as if I was chopping down a tree and they wouldn't break free.
You'll have to be creative with the setup but if you're doing this repair yourself then I'm sure you will be fine. There is a lot of trial and error.
First off though, before trying to hammer the bolts out, tape a socket to the threaded end of the bolt, pretty sure it is a 10mm on the one end. This way you won't destroy the bolt and when you go to use the press you'll have a flat surface to press on. The issue when trying to hammer the bolt out is that the bushing absorbs the shock of the hit and the bolt and sleeve move together. When using the press, you have to figure out a way to hold the sleeve while putting pressure on the bolt. The shackle of the shock has a small enough opening that it will hold the sleeve still for the first few cranks until the shackle itself starts to bend. At this point I cut the shackle off the shock, removed the shock and spring, and then used a crescent wrench in between the bolt head and the sleeve in order to start applying pressure again through the ball joint press. You'll probably wreck a crescent wrench in this process as well.
I was only able to press the bolt half way out until the ball joint press I had started to strip itself, so I cut the bolt head off as close to the bushing as I could, flipped the press the other way and then pressed out the bolt from the bushing in the opposite direction. Filed the inner sleeve, replaced the bolt, installed the shocks and called it a day.
