That or heat and judicious use of a slide hammer if I can figure out how to get the hooks around the axle to hook on the back. I'm kind of afraid of bending that plate and making things worse if I smack a cold chisel or wedge in there. Thanks for the encouragement.
FWIW this is what the new hubs look like Attachment 275738 It's that little ridge that's corroded into the plate and won't let go.
