I’ve got one on order from partsouq, not an enormous rush but was hoping to get it done today, since i’m on vacation.
Don’t let your air chisel get close to cast aluminum

from the bottom, I was rolling the edges of the flange in, still wouldnt come out... so I removed the bushing core and was pushing more and more of the bushing wall inwards, slipped and went through the center hole and landed on the lip that diameter you see in the picture. If you aren’t familiar with that bushing/bore, the face you see only gets the bushing core through it, and it just about bottoms out on the face.
Moral of the story, don’t be stupid like me
