bushing

Tryng to get the old bushings out of the swing arm. They are not plastic so the hack saw is a no go. Tried heat and no luck. Any ideas?

Hey guys. Anyone out there ever replaced the inner bushing on a fork lower (the teflon coated one)? Got a nicely polished lower that has a bushing where the teflon looks a bit worn. There has to be a better way than shopping around for an entire replacement lower and discarding an otherwise...
