You can rent a bushing press from autozone and try to press them out.

 

I have my old LCA still, and they look totally the same. Although I remember that part being harder to remove than the other. What you need to do is, set it on fire, there's still rubber between the big metal sleeves (it's actually 2 pieces cut in half) and the smaller aluminum sleeves, trust me. You'd know when it's in flames when even if you remove the torch it's still on fire, then pry the small aluminum sleeves first before the bigger metal sleeves as hard as you can while torching it, it is really stuck on there pretty good as you may think because the flame can't get through the left over rubber in between the 2 sleeves. But it is possible.

PS; I don't think that there's a difference between Supra and SC LCA's, 'cause I was also under the assumption that that might be the case on mine when I replaced just one side from a pick-your-parts shop.

 

Well in my searching I have found that the supra bushing is indeed different than the sc one which is what I am finding out now one side bushing went right in but the other is a pita and is more like a ball socket which won't allow it to come out.

When I eyeball the prothane bushing that I have it is smaller than the supra one as well.

I had an oaw torch on it so I am sure there is no rubber left at all lol.
