Lower control arm bushings

A friend of mine got his idea posted in Mopar Action mag.
toss a couple large washers (or some equivelant) inside, then use a chisle and hammer to fold the lip in capturing the washers.
Then flip over and use a steel rod against the washers and use a BFH to drive it out.

I have a welder so I like welding on a chunk of steel and beating on that.
