Dont need a press torch the old bushing out and beat the new one in with a large socket. Press does make it easier but can be done without.

 

one on the right is the front eye, I did mine in the truck as the work to remove both springs was going to be more than the work to get the bushings out and replaced. I drilled as many holes through the rubber as I could to perforate it and then walked the drill around until the center was free from the rubber. Knocked the remaining rubber out, used my air chisel to roll in and then slice the outer shell. Polished out the spring eye and greased it up, Then used an ~8" c-clamp and a plate as a makeshift press. Took some serious effort to get it pressed in but once it's in flush it's good to go.
